ensurepip optionally installs or upgrades 'pip' and 'setuptools' using the version of those modules bundled with Python. The internal PIP installation routine by default temporarily uses its cache, if it exists. This is undesirable as Python builds and installations may be independent of the user running the build, whilst PIP cache location is dependent on the user's environment and outside of the build environment. At the same time, there's no value in using the cache while installing bundled modules. This change disables PIP caching when used in ensurepip.

@pradyunsg Opinions? |

Is there still I need to do about this PR? No pressure, just checking :) Should I do anything about bedevere/news, or is it something that a maintainer would take care of when merging? |
|
I've also just asked on the bug tracker for a review. |

I believe you'll need to fix the test failures and add a news item. |
