Anyone who met the same problem before and can give me some tips to solve it?

I had the same problem.
My solution:

For Python 3

sudo apt-get install python3-pip

For Python 2

sudo apt-get install python-pip

With macOS 10.15 and Homebrew 2.1.6 I was getting this error with Python 3.7. I just needed to run:

python3 -m ensurepip

Now python3 -m pip works for me.

On Mac using brew is a better option as apt-get is not available.
Command:

brew install python

In case you have both python2 & python3 installed on machine

python2.7 -m ensurepip --default-pip

simply should solve the issue.

If instead you are missing pip from python 3 then simply change python2.7 to python3 in the command above.

On some kind of Linux, like distros based on Debian, you might want to consider updating your ‘apt-get‘ first, in case you are installing python-pip through it.

sudo apt-get update

This might help apt-get to update its indexes and locate the python-pip package.
After this, u might install pip like this-

sudo apt-get install python-pip (Python2)
sudo apt-get install python3-pip (Python3)

I encountered the same error with Python 3.8.6 on MacOS Big Sur.

Whether I used pip or pip3 I’d get this error:

 File "/Users/marcelloromani/dev/<repository>/venv/bin/pip", line 5, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'

It turns out my virtualenv was out of date.
This fixed the issue for me:

Remove the old virtualenv

$ deactivate
$ rm -rf venv

Initialise a new virtualenv

$ virtualenv venv
$ . venv/bin/activate

Install the new requirements then worked:

$ pip install -r src/requirements.txt

Try to re-install the pip
use curl command to download the get-pip.py file:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

if curl is not working then open this link :
get-pip.py

create a get-pip.py file in your directory
copy the code from this link and put it in the get-pip.py file and save the file in the same directory.
then run the command

python get-pip.py

If you get «No module named pip» in ubuntu, try this.

$python3 -m pip --version
/usr/bin/python3: No module named pip

$sudo apt-get install python3-pip

It worked for me.

After successful installation validate using

$python3 -m pip --version

To upgrade to latest pip version

$python3 -m pip install --upgrade pip

I ran into this same issue when I attempted to install the nova client.

spencers-macbook-pro:python-novaclient root# python  setup.py install    
running install
/usr/bin/python: No module named pip
error: /usr/bin/python -m pip.__init__ install   'pbr>=0.5.21,<1.0' 'iso8601>=0.1.4' 'PrettyTable>=0.6,<0.8' 'requests>=1.1' 'simplejson>=2.0.9' 'six' 'Babel>=0.9.6' returned 1

I use homebrew so I worked around the issue with sudo easy_install pip

spencers-macbook-pro:python-novaclient root# brew search pip
aespipe     brew-pip    lesspipe    pipebench   pipemeter   spiped  pipeviewer

If you meant "pip" precisely:

Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
spencers-macbook-pro:python-novaclient root# sudo easy_install pip

The commands should be similar if you use macports.

I know this thread is old, but I just solved the problem for myself on OS X differently than described here.

Basically I reinstalled Python 2.7 through brew, and it comes with pip.

Install Xcode if not already:

xcode-select –install

Install Brew as described here:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install Python through Brew:

brew install python

And you’re done. In my case I just needed to install pyserial.

pip install pyserial

I think none of these answers above can fix your problem.

I was also confused by this problem once. You should manually install pip following the official guide pip installation (which currently involves running a single get-pip.py Python script)

after that, just sudo pip install Django.
The error will be gone.

I encountered the issue ModuleNotFoundError: No module named 'pip' when I created a new Python 3 virtual environment using the command

python3 -m venv ~/venv/ontology    ## << note: "python3" (problematic)

which is a command often suggested (here, elsewhere). When I entered that venv, pip was nowhere to be found.

In the interim, since first using that command to create Python virtual environments, my system Python had upgraded (Arch Linux system updates) from Python 3.7.4 to Python 3.9.2.

The solution is to use the command

python -m venv <your_venv>  ## e.g. python -m ~/venv/ontology

When I did that (python -m ... not python3 -m ...), that venv now contained pip …

To upgrade pip within that venv, use

<your_venv_path>/bin/python -m pip install --upgrade pip

## e.g.
## /home/victoria/venv/ontology/bin/python -m pip install --upgrade pip

In terminal try this:

ls -lA /usr/local/bin | grep pip

in my case i get:

-rwxr-xr-x 1 root  root      284 Сен 13 16:20 pip
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2

-rwxr-xr-x 1 root  root      292 Сен 13 16:20 pip-3.4

So pip2 || pip2.7 in my case works, and pip

I am using Debian, but this solution can also be applied for Ubuntu.

Usually, pip comes with python by default, in order to check if pip is installed in your system run.

python -m pip --version

If pip is not there, install it using Aptitude Linux Package Manager,

# For Python 2
sudo apt install python-pip

# For Python 3
sudo apt install python3-venv python3-pip

I wouldn’t use the get-pip.py script in Debian/Ubuntu, because in the documentation page mentions the following.

Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.

Sources here and there.

this if your mac is not above big sur

and you installed py 3 —

I did this and I have no problems now

back to the legacy version of 2.7 I guess.

Here’s a minimal set of instructions for upgrading to Python 3 using MacPorts:

sudo port install py37-pip
sudo port select --set pip pip37
sudo port select --set pip3 pip37
sudo pip install numpy, scipy, matplotlib

I ran some old code and it works again after this upgrade.

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip.

my py version is 3.7.3, and this cmd worked

python3.7 -m pip install requests

requests library — for retrieving data from web APIs.

This runs the pip module and asks it to find the requests library on PyPI.org (the Python Package Index) and install it in your local system so that it becomes available for you to import

This error occurs when you try to use pip, but it is not installed in your Python environment. This can happen if you skip installing pip when installing Python or when creating a virtual environment, or after explicitly uninstalling pip.

You can solve this error by downloading pip using the following curl command

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then install pip by running:

python3 get-pip.py

If this does not work, you can use ensurepip to bootstrap the pip installer into an existing Pip installation or virtual environment. For example,

# Linux
python3 -m ensurepip --upgrade

# MacOS
python3 -m ensurepip --upgrade

# Windows
py -m ensurepip --upgrade

This tutorial will go through the ways to ensure pip is installed in your environment.

Summary

Install pip by Downloading get-pip.py

Download pip by running the following curl command:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

The curl command allows you to specify a direct download link. Using the -o option sets the name of the downloaded file.

Install pip by running:

python3 get-pip.py

Bootstrap pip using ensurepip

You can use ensurepip to bootstrap the pip installer into an existing Pip installation or virtual environment. For example,

# Linux
python3 -m ensurepip --upgrade

# MacOS
python3 -m ensurepip --upgrade

# Windows
py -m ensurepip --upgrade

Install pip using Operating System Specific command

If the above solutions do not work, you can try to install pip using the command specific to your operating system.

Installing pip for Linux

All major Linux distributions have Python installed by default. However, you will need to install pip. You can install pip from the terminal, but the installation instructions depend on the Linux distribution you are using. You will need root privileges to install pip. Open a terminal and use the commands relevant to your Linux distribution to install pip.

Installing pip for Ubuntu, Debian, and Linux Mint

sudo apt install python-pip3

Installing pip for CentOS 8 (and newer), Fedora, and Red Hat

sudo dnf install python-pip3

Installing pip for CentOS 6 and 7, and older versions of Red Hat

sudo yum install epel-release

sudo yum install python-pip3

Installing pip for Arch Linux and Manjaro

sudo pacman -S python-pip

Installing pip for OpenSUSE

sudo zypper python3-pip

Installing pip for Mac Operating System

You can install Python3 and pip3 using brew with the following command:

brew install python

Upgrading pip

You may also need to upgrade pip, which you can do with the following commands:

# Linux

Check pip and Python version

Ensure that the Python version in use matches the pip version. You can check versions from the command line using the --version flag. For example,

python --version

Python 3.8.8

pip --version

pip 21.2.4 from /Users/Research/opt/anaconda3/lib/python3.8/site-packages/pip (python 3.8)

Note that the –version returns the version of Python is 3.8.8, and the pip installer in use is for 3.8.

Recreate Virtual Environment

If you are using a virtual environment and the error persists despite trying the above solutions, you can recreate the environment. For example,

# deactivate environment

deactivate

# remove the virtual environment folder

rm -rf venv

# Initial a new virtual environment

python3 -m venv venv

# Activate on Linux/MacOS

source venv/bin/activate

# Activate on Windows (cmd.exe)

venvScriptsactivate.bat

# Activate on Windows (PowerShell)

venvScriptsActivate.ps1

In this article, we will look into how to solve «/usr/bin/python3: No module named pip» error which I believe is a pretty common error in a freshly built Linux System where python3 packages are not installed yet. pip is a very famous python package management tool frequently used by Python Programmers and developers to manage their application packages. If you don’t have pip installed before you are trying to install any of the python modules then you will always end up with "/usr/bin/python3: No module named pip" error just like what I encountered last night. While this may not be the only reason to have this error but this is the common most reason for lot of folks !!

So when I was trying to install a package using pip, I encountered below error in my Ubuntu 20.04 LTS System. You might be getting the same error in different Linux version.

root@cyberithub:~# python3 -m pip install --user pipenv
/usr/bin/python3: No module named pip

While this error can come due to multiple reasons but in most of the cases you will see this error because of pip package not installed in your System. So to solve this kind of error, you need to simply install pip package from the default Repo. For example, in my case I have used apt-get install python3-pip command to install this package in my System. More about PIP.

If you are using RHEL/CentOS 7 based Systems, then all you need to do in to enable the EPEL Repo and then install the package by using yum install python3-pip command. For RHEL/CentOS 8 based Systems, you can use dnf install python3-pip command.

yum install python3-pip 
dnf install python3-pip

After successful installation, you can verify the package version by using pip --version command as shown below.

root@cyberithub:~# pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

After installing the package I again tried to run the earlier command then this time I noticed that the command worked successfully and now it is not throwing "/usr/bin/python3: No module named pip" error as shown below. Hope this helps !!

Quick Fix: Python raises the ImportError: No module named 'pip' when it cannot find the library pip. The most frequent source of this error is that you haven’t installed pip explicitly with pip install pip. Alternatively, you may have different Python versions on your computer, and pip is not installed for the particular version you’re using.

Problem Formulation

You’ve just learned about the awesome capabilities of the pip library and you want to try it out, so you start your code with the following statement:

import pip

This is supposed to import the Pandas library into your (virtual) environment. However, it only throws the following ImportError: No module named pip:

>>> import pip
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    import pip
ModuleNotFoundError: No module named 'pip'

Solution Idea 1: Install Library pip

The most likely reason is that Python doesn’t provide pip in its standard library. You need to install it first!

Before being able to import the Pandas module, you need to install it using Python’s package manager pip. Make sure pip is installed on your machine.

To fix this error, you can run the following command in your Windows shell:

$ pip install pip

This simple command installs pip in your virtual environment on Windows, Linux, and MacOS. It assumes that your pip version is updated. If it isn’t, use the following two commands in your terminal, command line, or shell (there’s no harm in doing it anyways):

$ python -m pip install --upgrade pip
$ pip install pandas

💡 Note: Don’t copy and paste the $ symbol. This is just to illustrate that you run it in your shell/terminal/command line.

Solution Idea 2: Fix the Path

The error might persist even after you have installed the pip library. This likely happens because pip is installed but doesn’t reside in the path you can use. Although pip may be installed on your system the script is unable to locate it. Therefore, it is unable to install the library using pip in the correct path.

To fix the problem with the path in Windows follow the steps given next.

Step 1: Open the folder where you installed Python by opening the command prompt and typing where python

Step 2: Once you have opened the Python folder, browse and open the Scripts folder and copy its location. Also verify that the folder contains the pip file.

Step 3: Now open the Scripts directory in the command prompt using the cd command and the location that you copied previously.

Step 4: Now install the library using pip install pip command. Here’s an analogous example:

After having followed the above steps, execute our script once again. And you should get the desired output.

Understanding the “import” Statement

import pip

In Python, the import statement serves two main purposes:

Search the module by its name, load it, and initialize it.
Define a name in the local namespace within the scope of the import statement. This local name is then used to reference the accessed module throughout the code.

What’s the Difference Between ImportError and ModuleNotFoundError?

What’s the difference between ImportError and ModuleNotFoundError?

Python defines an error hierarchy, so some error classes inherit from other error classes. In our case, the ModuleNotFoundError is a subclass of the ImportError class.

You can see this in this screenshot from the docs:

You can also check this relationship using the issubclass() built-in function:

>>> issubclass(ModuleNotFoundError, ImportError)
True

Specifically, Python raises the ModuleNotFoundError if the module (e.g., pip) cannot be found. If it can be found, there may be a problem loading the module or some specific files within the module. In those cases, Python would raise an ImportError.

If an import statement cannot import a module, it raises an ImportError. This may occur because of a faulty installation or an invalid path. In Python 3.6 or newer, this will usually raise a ModuleNotFoundError.

How to Fix “ModuleNotFoundError: No module named ‘pip’” in PyCharm

If you create a new Python project in PyCharm and try to import the pip library, it’ll raise the following error message:

Traceback (most recent call last):
  File "C:/Users/.../main.py", line 1, in <module>
    import pip
ModuleNotFoundError: No module named 'pip'

Process finished with exit code 1

The reason is that each PyCharm project, per default, creates a virtual environment in which you can install custom Python modules. But the virtual environment is initially empty—even if you’ve already installed pip on your computer!

Here’s a screenshot exemplifying this for the pandas library. It’ll look similar for pip.

The fix is simple: Use the PyCharm installation tooltips to install Pandas in your virtual environment—two clicks and you’re good to go!

First, right-click on the pandas text in your editor:

Second, click “Show Context Actions” in your context menu. In the new menu that arises, click “Install Pandas” and wait for PyCharm to finish the installation.

The code will run after your installation completes successfully.

As an alternative, you can also open the Terminal tool at the bottom and type:

$ pip install pip

If this doesn’t work, you may want to set the Python interpreter to another version using the following tutorial: https://www.jetbrains.com/help/pycharm/2016.1/configuring-python-interpreter-for-a-project.html

You can also manually install a new library such as pip in PyCharm using the following procedure:

Open File > Settings > Project from the PyCharm menu.
Select your current project.
Click the Python Interpreter tab within your project tab.
Click the small + symbol to add a new library to the project.
Now type in the library to be installed, in your example Pandas, and click Install Package.
Wait for the installation to terminate and close all popup windows.

Here’s an analogous example:

I installed Python 3.4 on CentOS 7.3:

sudo yum install epel-release
sudo yum install python34.x86_64

There was python 2 installed before under

type python
python is hashed (/bin/python)

So version 3 is under python3:

type python3
python3 is hashed (/bin/python3)

On Windows, I have version 3.5 and the way I install packages is:

python -m pip install <package_name>

So I tried the same on CentOS but calling python3 instead of python:

python3 -m pip install psycopg2
/bin/python3: No module named pip

How do I install or enable pip in Python 3.4 on CentOS so that I can install packages?

For CentOS 7 you would need to run this:

sudo yum install python34-setuptools
sudo easy_install-3.4 pip

Edit: You should then be able to install using pip3 install <package>
