While programming, you get the ModuleNotFoundError: No module named ‘OpenSSL’ in Python. I will guide you to install it on operating systems. Please follow the following article.
What causes the ModuleNotFoundError: No module named ‘OpenSSL’ in Python?
The ModuleNotFoundError: No module named ‘OpenSSL’ error happens because you have not installed the ‘OpenSSL’ module to be able to use it or installed the wrong environment. I will do the installation in a virtual environment.
How to solve this error?
Install library ‘OpenSSL’
Install the ‘OpenSSL’ module. You can use Python pip. But note that you need to specify the exact version of Python you are using.
Example:
If you don’t have pip installed here is the solution for you in Python 3:
python3 -m pip install pyOpenSSL
If you use Python 3, use the pip3 statement as follows:
pip3 install pyOpenSSL
If you use Python 2, use the following pip command:
pip install pyOpenSSL
Install ‘OpenSSL’ on operating systems
I would install ‘OpenSSL’ according to your operating system.
Install ‘OpenSSL’ on Windows using pip
Before installing ‘OpenSSL’, you need to create a virtual environment. Using a virtual environment helps you avoid incompatibilities between packages and break the system if you install incompatible libraries with your operating system.
You can activate the virtual environment with the following command:
venv\Scripts\Activate.ps1
Then you can install the ‘OpenSSL’ module with the following command:
python3 -m pip install pyOpenSSL
If you do not have pip installed, use the following command:
python3 -m pip install pyOpenSSL
Install ‘OpenSSL’ on Mac using pip
Make sure you have installed Python and pip. Just like on Windows operating systems, you also need a virtual environment. Just like on Windows operating systems, you also need your virtual environment. You can activate the virtual environment with the following command:
source venv/bin/activate
Install ‘OpenSSL’ in the command prompt environment:
python3 -m pip install pyOpenSSL
Install module ‘OpenSSL’ by Anaconda
Anaconda is the most popular open-source Data Science platform available on Python. Install Anaconda first, create a virtual environment, and install ‘OpenSSL’.
To create an anaconda environment:
conda create -n OpenSSL python=3.8
Enable the project area you will see ‘OpenSSL’ in parentheses next to the line prompt:
source activate pyopenssl
Finally, install ‘OpenSSL’ with the command:
conda install -c anaconda pyopenssl
Import OpenSSL module
Once you have successfully installed the OpenSSL module, to use it, you need to import this module with the following syntax:
from OpenSSL import crypto import OpenSSL
Summary
Hopefully through the article you will successfully install and fix the ModuleNotFoundError: No module named ‘OpenSSL’ in Python. Depending on the operating system you use, choose the appropriate way. Thank you for reading!
