Root Cause

The requirement specifies a local version identifier (e.g., 1.0+local) which is not allowed in requirements files unless the package is available from a local index or direct URL.

generic

中文

要求指定了本地版本标识符（例如 1.0+local），除非包来自本地索引或直接 URL，否则在 requirements 文件中不允许使用。

Workarounds

  1. 85% success 
    Specify the package with a direct URL: package @ https://example.com/package-1.0+local.tar.gz.
  2. 80% success 
    Use a local index: pip install --index-url file:///path/to/index package==1.0+local.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    May install a different version than intended, causing compatibility issues.

  2. 90% fail

    Does not affect local version identifiers; still invalid.
