Root Cause

The requirement string has conflicting version constraints that cannot be satisfied simultaneously.

generic

中文

依赖要求字符串中存在相互冲突的版本约束，无法同时满足。

Workarounds

  1. 95% success Correct the version range to be non-contradictory 
    pip install 'package>=1.0,<2.0'
  2. 90% success Use a single version constraint 
    pip install 'package>=1.0'

Dead Ends

Common approaches that don't work:

  1. Reordering the constraints (e.g., '>=2.0,<1.0') 95% fail

    The conflict remains regardless of order; pip parses the entire set.

  2. Using a comma instead of a semicolon 90% fail

    Commas are valid separators; the issue is the logical contradiction.
