Root Cause

The same package is listed with different versions in the requirements file, causing ambiguity.

generic

中文

requirements文件中同一包列出了不同版本，导致歧义。

Workarounds

  1. 95% success Remove duplicate and keep only one version 
    # Edit requirements.txt to keep only one line
numpy==1.22.0
  2. 90% success Use pip-compile to resolve dependencies automatically 
    pip install pip-tools
pip-compile requirements.in

Dead Ends

Common approaches that don't work:

  1. Keeping both entries 50% fail

    Pip will use the last occurrence, which may not be intended.

  2. Ignoring the warning 60% fail

    May install unexpected version; conflicts later.
