Error after upgrading Pip: "ImportError: cannot import name 'main'"

When attempting package installations using Pip, an "ImportError: cannot import name 'main'" error may arise. This issue is often encountered after upgrading Pip, especially on Debian-based systems where Pip is managed by the package maintainer.

The root of this error lies in the introduction of changes to the internal structure of Pip 10.x. The "pip3" command, provided by the package maintainer, still references the previous structure and is unable to locate the updated components.

To resolve this issue, it is recommended to avoid upgrading Pip through the sudo pip install pip --upgrade command. Instead, consider using a virtual environment to isolate Pip installations and avoid potential conflicts.

If you have already upgraded Pip and encountered the import error, you can attempt to recover the original Pip3 binary by executing the following commands with sudo privileges:

• python3 -m pip uninstall pip
• sudo apt install python3-pip --reinstall

Alternatively, you can use the command python3 -m pip ... instead of pip3 to bypass the upgraded package manager. However, this is not recommended as it may lead to further system conflicts.
