Where is pip cache folder?

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?

Method 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.

Method 2

It depends on the operating system.

With pip 20.1 or later, you can find it with:

pip cache dir

For example with macOS:

$ pip cache dir
/Users/hugo/Library/Caches/pip

Method 3

Pythonic and cross-platform way:

import pip
from distutils.version import LooseVersion

if LooseVersion(pip.__version__) < LooseVersion('10'):
    # older pip version
    from pip.utils.appdirs import user_cache_dir
else:
    # newer pip version
    from pip._internal.utils.appdirs import user_cache_dir

print(user_cache_dir('pip'))
print(user_cache_dir('wheel'))

Under the hood, it normalizes paths, manages different locations for exotic and ordinary operating systems and platforms, performs Windows registry lookup.

It may worth mentioning, if you have different Python versions installed, 2.x’es and 3.x’es, they all do share the same cache location.

Method 4

You can backup the associated wheel rather than attempting to perform a backup of the cache folder.

Download the wheel for csselect of version 0.9.1 into /tmp/wheelhouse:

pip wheel --wheel-dir=/tmp/wheelhouse cssselect==0.9.1

Install the downloaded wheel:

pip install /tmp/wheelhouse/cssselect-0.9.1-py2-none-any.whl
