Uninstalling Pip-Installed Packages in Virtual Environments

If you're working with a virtual environment and want to remove all packages installed via pip, there are several approaches you can take.

Method 1: Using Pip Freeze with Xargs

This method involves using Pip Freeze to generate a list of installed packages, and then using Xargs to pass this list to Pip Uninstall for bulk uninstallation.

pip freeze | xargs pip uninstall -y

Method 2: Excluding Editable Packages

If you have packages installed via version control systems (VCS), you can exclude them from the list before uninstallation.

pip freeze --exclude-editable | xargs pip uninstall -y

Method 3: Handling Direct GitHub/GitLab Installations

Packages installed directly from GitHub or GitLab may have "@" appended to their names. To handle these, use the following command:

pip freeze | cut -d "@" -f1 | xargs pip uninstall -y
