Root Cause

The maintainer yanked a release on PyPI; pip still installs it if it is the only version satisfying constraints, but warns loudly.

generic

中文

维护者在 PyPI 上撤回了某个发布；如果它是唯一满足约束的版本，pip 仍会安装，但会发出警告。

Workarounds

  1. 90% success 
    Pin to a non-yanked version:
  pip install 'foo==1.2.2'
Or allow any non-yanked:
  pip install 'foo!=1.2.3'
  2. 90% success 
    Check available versions:
  pip index versions foo
Then choose the latest non-yanked release.

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Upgrade only moves to a newer version if one is available; if the yanked release is the only match, the warning persists.

  2. 95% fail

    That flag controls script location warnings, not yanked-version warnings.
