: No module named 'passlib'

Hello! It looks like you're encountering an error message saying "No module named 'passlib'". This error typically occurs when the Passlib library is not installed or not found in your Python environment. Passlib is a password hashing library for Python.

To resolve this issue, you can try installing the Passlib library using pip, which is the package installer for Python. Open your terminal or command prompt and run the following command:

pip install passlib

Make sure you have an active internet connection, and pip will download and install the Passlib library for you. Once the installation is complete, you should be able to import and use the Passlib module in your Python program without any issues.

If you are using a virtual environment, ensure that it is activated before running the pip install command. Additionally, double-check that you are using the correct Python environment and that pip is installed and accessible in that environment.

I hope this helps! Let me know if you have any further questions.
