Question or problem about Python programming:
Where is Python pip cache folder? I had error during install and now reinstall packages using cache files
Where is that directory? I want 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 learn to how 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 ?
How to solve the problem:
Solution 1:
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
Docs:
- https://pip.pypa.io/en/stable/reference/pip_cache/
- https://pip.pypa.io/en/stable/reference/pip_install/#caching
Solution 2:
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
\pip\Cache
Wheel Cache
pip will read from the subdirectory wheels within the pip cache directory and use any packages found there. [snip]
https://pip.pypa.io/en/latest/reference/pip_install/#caching
The location of the cache directory can be changed via the command line option --cache-dir.
Solution 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.
Solution 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
