If I remove --no-cache-dir it works fine.

Can you verify #2856 fixes it for you.

Seems that this is still broken if using env var:

$ PIP_NO_CACHE_DIR=1 pip install gunicorn

@rhcarvalho You should log a new issue (not sure if anyone sees your comment).

Am running into this issue verbatim. Using Python 2.7 and pip 18.0. Here's the log.

[pradyunsg]

@jakirkham It is not the same error verbatim.

It's been fixed in #5764 and would be released sometime next month.

[jakirkham]

Hmm...maybe I missed something. Happy to trust your judgment. 🙂
