Pip error could not find a version that satisfies the requirement

Sometimes you get an error when you're trying to install a Python package using pip. It looks like this:

Sometimes you get an error when you’re trying to install a Python package
using pip. It looks like this:

Could not find a version that satisfies the requirement (from versions:)
No matching distribution found for

Some probable reasons for this error are:

  1. PyPI server isn’t responding to your requests. It can happen either because
    the PyPI server is down or because it has blacklisted your IP address. This
    happened to me once when I was trying installing packages on a server.
    This can be fixed by using a proxy with pip. See the solution below.

  2. You’re running an older pip (especially on Mac). This can be fixed by
    upgrading your pip.
    See this post on Stack Overflow.
    Thanks to Anupam Jain who pointed this in a comment.

  3. The package you’re trying to install is not available for your Python version.

  4. The package is not available for your operating system. This is a rare case
    and only happens when the package is not pure-Python, i.e. it’s been
    partially written in C or Cython. Such a package needs to be compiled for
    every operating system (Windows/Mac/Linux) and architecture (32-bit/64-bit).
    Suppose a package has only been compiled for Windows 64-bit, then you’ll get
    this error if you try to install it on Windows 32-bit, or any other
    OS.

  5. The package is not present on PyPI server. In this case pip will not work. So
    you’ll have to download and install the package manually from Github or wherever
    it is available.

Solution¶

I had this issue because PyPI server had blacklisted the IP
of my hosting provider, the obvious solution was to make pip install via a proxy.

But to see if that’s also the case with you, you can test it like this:

$ curl https://pypi.org

The requestors Network has been blacklisted due to excessive request volume. 
If you are a hosting customer, please contact your hosting company's support. 
If you are the hosting company, please contact infrastructure-staff@python.org to resolve

If you see the message similar to above, that means your IP has also been
blacklisted by https://pypi.org.

If you don’t see this message then the reason for the pip error could be that you’re using
an older version. See this post on Stack Overflow
for a solution.

Anyways, this can be fixed by using a proxy with pip.

Supplying a proxy address to pip is easy:

$ pip install -r requirements.txt --proxy address:port

Above, address and port are IP address and port of the proxy.

To find proxies, just search Google for proxy list.

Other things that I tried¶

These are some other things that I tried to get rid of this issue.
Although they didn’t work for me, but they might work for you.

  1. Changing DNS resolver of my server.
    This makes sense if your server’s DNS resolver can’t find PyPI servers.
  2. Reconfiguring SSL, reinstalling CA certificates.
    This makes sense if you don’t have updated CA certificates which are used by
    PyPI servers.
  3. Downloading packages using wget.
    This is an alternative way to install Python packages. Download them via wget
    and then install them using python setup.py install. In my case, the server was
    blacklisted by PyPI so I was getting a 403 Forbidden error.
  4. Downloading packages using curl.
    Alternative to wget. In my case I didn’t get a 403 error but rather it just
    created invalid tarball files, instead of actually downloading them.
  5. Downloading packages using git or hg.
    If your desired packages have git or hg repositories that you can clone, this
    is a good workaround.

Question

When we use Python to develop, we usually use some useful third-party libraries. It is recommended to use pip to install, such as installing pandas 

python -m pip install pandas

Enter fullscreen mode

Exit fullscreen mode

Under normal circumstances, there is no problem, but some small partners will encounter installation failures such as pip installation of third-party libraries and errors, pip install stuck and other installation failures.

For example, the following is the code that pip installs a third-party library to report an error 

Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None))...

Enter fullscreen mode

Exit fullscreen mode

I will summarize here the solutions for the failure of Python to install third-party libraries.

Solution

Option 1

The Python environment factor reports an error, check whether Python and pip under your computer are installed normally 

# Print the current Python version
python --version

Enter fullscreen mode

Exit fullscreen mode

If the Python version information is printed out normally after running the above command, it means that it is normal. If an error is reported, it may be that the environment variables are not configured when installing Python under Windows. You can configure the Python environment variables, or directly reinstall Python to the C drive, so that there will be no problem with environment variables. 

# print pip version
python -m pip --version

Enter fullscreen mode

Exit fullscreen mode

If the pip version information is printed out normally after running the above command, it means that it is normal. If an error is reported, you can use this command to install and upgrade 

python -m ensurepip --upgrade

Enter fullscreen mode

Exit fullscreen mode

If you can’t run pip yet, you can also install pip manually

  1. Open https://bootstrap.pypa.io/get-pip.py
  2. Right click on the page — save as — save anywhere
  3. Execute python get-pip.py on the command line of the directory where the get-pip.py file is located

Another advantage of manually installing pip is that you can directly use global pip to install dependent packages, such as 

pip install pandas

Enter fullscreen mode

Exit fullscreen mode

Option 2

Although pip is installed normally, sometimes it will prompt you that the version of pip is too low 

WARNING: You are using pip version 22.0.3; however, version 22.0.4 is available.
You should consider upgrading via the '/usr/local/bin/python -m pip install --upgrade pip' command.

Enter fullscreen mode

Exit fullscreen mode

Run the following command to upgrade pip 

python -m pip install --upgrade pip

Enter fullscreen mode

Exit fullscreen mode

Option 3

The third-party package name or version number is entered incorrectly. For example, I install a package called padas in the command line terminal 

python -m pip install padas

Enter fullscreen mode

Exit fullscreen mode

The following error will appear 

ERROR: Could not find a version that satisfies the requirement padas (from versions: none)
ERROR: No matching distribution found for padas

Enter fullscreen mode

Exit fullscreen mode

The error tells me that I typed padas, that the package and its version number cannot be found. At this time, you need to check whether the package name is entered correctly, the correct one should be pandas. (Of course, after the article is published, some developers may have released this package, which is only for demonstration)

There is also a problem that the version number may not exist. For example, I install a higher version of pandas 

python -m pip install pandas==6.5

Enter fullscreen mode

Exit fullscreen mode

The following error will appear 

ERROR: Could not find a version that satisfies the requirement pandas==6.5 (from versions: 0.1, 0.2, 0.3.0, 0.4.0, 0.4.1, 0.4.2, 0.4.3, 0.5.0, 0.6.0 , 0.6.1, 0.7.0, 0.7.1, 0.7.2, 0.7.3, 0.8.0, 0.8.1, 0.9.0, 0.9.1, 0.10.0, 0.10.1, 0.11.0, 0.12 .0, 0.13.0, 0.13.1, 0.14.0, 0.14.1, 0.15.0, 0.15.1, 0.15.2, 0.16.0, 0.16.1, 0.16.2, 0.17.0, 0.17.1 , 0.18.0, 0.18.1, 0.19.0, 0.19.1, 0.19.2, 0.20.0, 0.20.1, 0.20.2, 0.20.3, 0.21.0, 0.21.1, 0.22.0, 0.23 .0, 0.23.1, 0.23.2, 0.23.3, 0.23.4, 0.24.0, 0.24.1, 0.24.2, 0.25.0, 0.25.1, 0.25.2, 0.25.3, 1.0.0 , 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5, 1.2.0, 1.2 .1, 1.2.2, 1.2.3, 1.2.4, 1.2.5, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.4.0rc0, 1.4.0 , 1.4.1)
ERROR: No matching distribution found for pandas==6.5

Enter fullscreen mode

Exit fullscreen mode

Obviously, this version number cannot be found, and it tells you all the version numbers that can be installed. We only need to select a version number that we need, or install the latest version by default without specifying a version number.

Option 4

The network quality and communication speed are different in different place, and the pip installation of dependencies will also encounter network timeout problems, such as the following errors 

raise ReadTimeoutError(self._pool, None, 'Read timed out.')
pip._vendor.requests.packages.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='pypi.org', port=443): Read timed out.

Enter fullscreen mode

Exit fullscreen mode

It indicates that the network has timed out, and there is a problem connecting to pypi.org. This is the website hosting the python dependencies, and all pip packages are published on it.

We can set a longer timeout, because the network in most places is not completely unconnectable, but the speed is a bit slow. Here the --default-timeout is set to 200s 

python -m pip --default-timeout=200 install pandas

Enter fullscreen mode

Exit fullscreen mode

Set a little more timeout, go have a cup of tea and wait for a while, and it may be downloaded.

Option 5

If you haven’t downloaded it after drinking tea, then consider changing the mirror source. For example, we switch to the mirror source of Tsinghua University. 

# --index-url can be abbreviated as -i
python -m pip install --index-url https://pypi.tuna.tsinghua.edu.cn/simple/ pandas

Enter fullscreen mode

Exit fullscreen mode

In addition to the official source and Tsinghua mirror source

  • Tsinghua: https://pypi.tuna.tsinghua.edu.cn/simple/
  • Official: https://pypi.org/

There are other mirror sources you can try

  • Aliyun: https://mirrors.aliyun.com/pypi/simple/
  • Douban: https://pypi.douban.com/simple/
  • Beijing Foreign Studies University https://mirrors.bfsu.edu.cn/pypi/web/simple/

Option 6

In addition to switching mirror sources, pip officially provides a variety of ways to install dependent packages

  1. Download the dependency package in advance, and then install it directly from the local path

For example, we can download the pandas distribution package file from the pip official website, and then execute the installation command in the directory where the local dependency package is located.

Install from Source Distribution 

python -m pip install pandas-1.4.1.tar.gz

Enter fullscreen mode

Exit fullscreen mode

or install from Built Distributions 

# Buildpacks for Windows platforms only
python -m pip install pandas-1.4.1-cp310-cp310-win_amd64.whl

Enter fullscreen mode

Exit fullscreen mode

List of all pandas distributions: pandas download files

  1. To install from any VCS (version control systems), use the following command format 
python -m pip install -e "vcs+protocol://repo_url/#egg=pkg&subdirectory=pkg_dir"

Enter fullscreen mode

Exit fullscreen mode

  • vcs: version control system name
  • protocol: protocol
  • repo_url: repository url
  • egg: package name
  • subdirectory: If the package is not in the project root directory, specify the subdirectory name

For example, install the pandas library directly from github 

python -m pip install git+https://github.com/pandas-dev/pandas.git#egg=pandas

Enter fullscreen mode

Exit fullscreen mode

This method will pull the latest code from github for local construction, which takes a long time, and is usually the development version.

pip supports a lot of version control systems and protocols, see VCS Support

  1. Installation from github also supports manual local installation, clone the github repository of the dependent package directly, and execute it in the project directory 
python setup.py install

Enter fullscreen mode

Exit fullscreen mode

In this way, the library built by this project is directly installed. In essence, it is similar to the remote method of using github. It needs to be compiled locally. It is usually used in the local development stage, or if you want to try the latest features of the project.

However, if you have network problems through pip install, this way of installing through github usually also has certain network problems.

Option 7

I have tried several of the above solutions, but none of them can perfectly meet my needs.

  • Although a long timeout is set, sometimes the network is very slow, and no matter how long the timeout is, it is a waste of time.
  • Compared with the official website, the mirror source has a slightly delayed synchronization time. The official pypi.org dependency package is the most stable. The same problem is also common in the npm package management of front-end development. The mirror source sometimes has unpredictable errors, and it is often fixed by switching to the official source (refer to NPM Install Error Guide).
  • If you directly download the source package to build, because many Python libraries are written by foreigners, the website is not in your country, the download speed is very slow when visiting other countries’ websites, downloading from github is just as slow (refer to GitHub Clone Is Very Slow).

We can consider some more scientific ways to surf the Internet to speed up access to the official website. After the acceleration, directly use pip install to install any third-party library. Basically, it can be completed in a few seconds. There is no need to set a timeout period, no need to switch mirror sources, and no need to worry about the delay of the installation package version. If you want to download the source package from the pip official website or installing Python third-party libraries remotely using github is very fast.

In addition, there are the following benefits

  • When you access some Python third-party library documents, you can also speed up access, such as pandas official website https://pandas.pydata.org/
  • When you go to github to learn the source code of open source projects, and use git clone to pull github open source projects, the speed is significantly improved
  • The technical documents searched by Google are often more accurate, and the top of the search results are the highly praised answers on stackoverflow, which are very useful
  • Visit some other great tech sites
