I get an error when pip builds wheels for the cryptography package.
Error:

Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
I have already installed OpenSSL and set the environment variables as suggested in this post yet the problem persists. My setup details:
- System — Windows 10
- Python — 3.8
- Pip — 19.3.1

In my case (windows 10 + conda) updating pip fixed the problem:
python -m pip install --upgrade pip

Setting cryptography to version 2.8 in requirements.txt fixed the issue.

TLDR;
Try using cryptography==3.1.1
Details:
This happened on Python 3.9.0 on Windows 10 PC.
I had the following in requirements.txt
cryptography==2.8
I removed the version and kept only cryptography in requirements.txt file like below
cryptography
Saved the requirements.txt and then I ran
pip install -r requirements.txt
It installed successfully.
Then I freeze the requirements.txt by running the following command
pip freeze > requirements.txt
Then the requirements.txt got updated with cryptography==3.1.1

Ran into this issue, and the solution is actually in the message when pip attempts to install openssl before cryptography:
generating cffi module 'build/temp.linux-x86_64-3.7/_openssl.c'
running build_rust
=============================DEBUG ASSISTANCE=============================
If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation.html for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq.html
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation.html#rust
5) If you are experiencing issues with Rust for *this release only* you may
set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.
=============================DEBUG ASSISTANCE=============================
Simply running the pip update command appeared to work for me:
pip install -U pip
Which updated pip from version 18.0 to version 21.0.1

I faced this issue on macOS Monterey (version 12.2.1) Apple M1 Pro. I followed Cryptography installation documentation and it helped me resolve the issue.
brew install openssl@1.1 rust
env CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS=1 LDFLAGS="$(brew --prefix openssl@1.1)/lib/libssl.a $(brew --prefix openssl@1.1)/lib/libcrypto.a" CFLAGS="-I$(brew --prefix openssl@1.1)/include" pip3 install cryptography

You can use the lastest version with
python3 -m pip install --no-use-pep517 cryptography
worked for me with ubuntu:18.04 on arm32v7
(instead as suggested by the error message install the full rust compiler and build-essentials, or upgrading pip (what had no effect on ubuntu:18.04 on my armbian))

I got this error trying to install Scrapy with Python 3.8.1 on Windows 10, but its solved installing the last version of pip (19.3.1 in my case) and all works using pip in this way:
python -m pip install scrapy --user

I have faced same issue and tried to install openssl with mentioned step but still was not able to proceed for windows 10. Later I upgraded pip to latest version and tried again and it worked without any issue.
I would recommend to upgrade pip to latest version and give a try before proceeding for installing openssl

I had the same issue. pip3 version was 19.* after upgrade it works
sudo -H pip3 install --upgrade pip
answered Jun 11, 2021 at 18:26
You can try to install cryptography==3.1.1 package instead of cryptography 35 version.
pip install cryptography==3.1.1
If still you are facing challenges in cryptography package integration.
You can resolve that by the following steps.
python -m pip install --upgrade pip
sudo pip install -U pip setuptools

I had this problem and i just installed rust and problem fixed for me
You can install end version of cryptography after installing rust programming languege(dont try pip install rust, its not python package)

Just updating pip
python -m pip install —upgrade pip
answered Sep 22, 2022 at 22:26
I did not install the latest version of Scrapy, then it worked for me. Instead of installing version 2.6.3, I installed 2.6.2:
pip install Scrapy==2.6.2
I use PyCharm 2022.2.3 (Professional Edition) on Windows.

error: can't find Rust compiler
If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
To update pip, run:
pip install --upgrade pip
and then retry package installation.
If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
This package requires Rust >=1.41.0.

,Try using cryptography==3.1.1,Then the requirements.txt got updated with cryptography==3.1.1
This happened on Python 3.9.0 on Windows 10 PC.
I had the following in requirements.txt
cryptography==2.8
I removed the version and kept only cryptography in requirements.txt file like below
cryptography
Saved the requirements.txt and then I ran
pip install -r requirements.txt
It installed successfully.
Then I freeze the requirements.txt by running the following command
pip freeze > requirements.txt

error: can't find Rust compiler
If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
To update pip, run:
pip install --upgrade pip
and then retry package installation.
If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
This package requires Rust >=1.41.0.

Answer by Issac Jacobs
PEP 517 has no support for direct installs from source, with everything being built as a wheel and installed from that. That’s a deliberate design decision. However, pip introduced the —no-binary option specifically to allow for packages that cannot be installed via wheel (see this comment and this issue).,I think it’s be important to make the message clear: pip will still be able to install from sdists, but it will do so by building a wheel locally and installing that. This has been the default way to handle sdists for some time, but the —no-binary option currently overrides it.,At the moment, —no-binary disables PEP 517, but that’s not a long-term solution as we intend (at some point) to remove the legacy «install via setup.py» code path from pip.,However, pip introduced the —no-binary option specifically to allow for packages that cannot be installed via wheel (see this comment and this issue ).

Install wheel files directly instead of extracting them to a temp directory. (#6030),Fix detection of existing standalone pip instance for PEP 517 builds. (#9953),Creates download cache directory if not existing.,Speed up installing a directory in certain cases by creating a sdist instead
of copying the entire directory. (#2535)
ERROR: Cannot uninstall foobar 0.1, RECORD file not found. You might be able to recover from this via: 'pip install --force-reinstall --no-deps foobar==0.1'.
Environment Details
When a user/admin installs the One-Drive tool, the installation starts and errors with the following error message on the Alteryx Designer:
- Alteryx Designer
- Any version which is 2020.3 or below
- Affects all the Python based Data Connectors
- Google BigQuery
- DynamicsCRM
- Azure Data Lake Store
- OneDrive
- PowerBI
- Salesforce 4.0 and above(Python based)
Cause
This is a known issue(DE28032) — which is caused because of the missing cryptography version on the requirements.txt file.
Please note — This error can occur for any Python based Data Connectors like — Google BigQuery, DynamicsCRM, ADLS, OneDrive, PowerBI, Salesforce 4.0 and above
Resolution
Following steps are the workaround, in order to resolve the issue. Please note — As this error can occur to any of the python based Data Connector tools, you may need to edit the «requirements.txt» file for the Input or Output based connectors, for each category.
For example, Google Big Query, ADLS, OneDrive, Salesforce — all these python based tools have both Input and Output connectors, and each of the input/output folders have their own requirements.txt file, which you need to edit to fix this error.
Workaround:
- Create a new folder(for example — OneDriveTool) and place your downloaded .yxi file(in this case one_drive_v1.0.2.yxi)
- Ensure that you are able to see the file extension on this yxi file. If you do not see the .yxi extension, you may need to enable «File name extensions» check box under the «View» menu of the File Explorer:
- Rename this .yxi file to .zip file, by right clicking and renaming the extension, as below:
- Once it is renamed to .zip file, right click and extract all files in this folder location:
- You would see two folders — One for Onedrive Input and the other for OneDrive Output. Please note — you need to make the changes from the below steps 1 and 2 for both the OneDrive Input folder and the OneDrive Output folder.
- Navigate into the newly extracted folder(OneDrive Input and OneDrive Output) and locate the rquirements.txt and open it
- Add cryptography==2.9.2 to the first line and save it
- Please apply the above change for the OneDrive Input and OneDrive Output folders — i.e — you would be editing the same file(requirements.txt) in each of the OneDrive Input / Output folder.
- After saving, select all the files on this OneDrive folder, where you have the extracted files, right click and select «7-zip» —> «Add to one_drive_v1.0.2.zip» to rezip the changes.
- This will archive all the extracted files into a new zip file. Now, rename this zip file, to .yxi, as below:
- After renaming, reinstall the tool set by re-running the .yxi file installer
