Root Cause

The requested package version does not exist on the configured index, or the package name is misspelled, or the index is unreachable.

generic

中文

请求的包版本在配置的索引上不存在，或包名拼写错误，或索引不可达。

Workarounds

  1. 90% success 
    Run `pip index versions foo` to list available versions, then install an existing one.
  2. 85% success 
    Check spelling and use `pip install foo` without pinning, or specify `--extra-index-url https://pypi.org/simple`.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    The version genuinely does not exist; retrying does not change index contents.

  2. 85% fail

    pip version is unrelated to index availability.
