In this article, we’ll explore how to fix the Python SSL Extension Compilation Error in Ubuntu 22.04. This error is typically displayed as “The Python ssl extension was not compiled. Missing the OpenSSL lib?” and usually occurs when installing Python via Pyenv.
Understanding the Error
Before we delve into the solutions, it’s crucial to understand what the error means. The error message indicates that the Python SSL extension was not compiled due to the absence of the OpenSSL library. OpenSSL is a robust, commercial-grade, and full-featured toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols.
Before starting, ensure you have administrative access to your Ubuntu 22.04 system and that you have a stable internet connection.
Solution 1: Installing libssl-dev
The first solution to this problem is to install the OpenSSL development package,
libssl-dev. This package contains the development libraries, header files, and manpages for libssl and libcrypto.
libssl-dev, open a terminal and run the following command:
sudo apt install libssl-dev
Solution 2: Force Remove and Reinstall OpenSSL
If the error persists after installing
libssl-dev, you may need to force remove and reinstall OpenSSL.
First, uninstall the current version of OpenSSL with the following command:
brew uninstall --force openssl
Next, clean up any older versions of OpenSSL and clear the brew cache using these commands:
brew cleanup -s openssl brew cleanup --prune-prefix
Finally, reinstall OpenSSL with:
brew install openssl
Solution 3: Reinstall OpenSSL with apt
If the above solutions don’t work, you can try reinstalling OpenSSL using apt. This can be done with the following command:
sudo apt reinstall openssl
Solution 4: Check PyOpenSSL Installation
Another potential solution is to ensure that PyOpenSSL is installed. PyOpenSSL is a Python binding to OpenSSL, which provides a high-level interface to the functions in OpenSSL.
To install PyOpenSSL, use the following command:
pip install pyopenssl
If pip is not installed, you can install it first using:
sudo apt install python-pip
The Python SSL Extension Compilation Error in Ubuntu 22.04 can be a bit tricky to resolve, but the solutions provided in this article should help you fix the issue. If you’re still encountering problems, consider reporting the issue on the Pyenv GitHub page for further assistance. Remember, the key to resolving such issues is understanding the error and methodically applying the appropriate solutions.
Pyenv is a popular Python version management tool that allows you to easily switch between multiple versions of Python on your system.
You can check the version of Python installed on your system by opening a terminal and running the command
