python - Where is pip cache folder?

Question

Where is Python pip cache folder? I had an error during install and now reinstall packages using cache files. Where is that directory? I want to backup them for install in the future. Is it possible?

For example, I have this one

Using cached cssselect-0.9.1.tar.gz

I searched google for this directory but anything I saw, is learning how to install from a folder, I want to find default cache directory. And another question, these cache files will stay in that directory or will remove soon?

Answer 1

The default location for the cache directory depends on the Operating System:

Unix

~/.cache/pip and it respects the XDG_CACHE_HOME directory.

macOS

~/Library/Caches/pip

Windows

<CSIDL_LOCAL_APPDATA>pipCache

Wheel Cache

pip will read from the subdirectory wheels within the pip cache directory and use any packages found there. [snip]

The location of the cache directory can be changed via the command line option --cache-dir.
