Root Cause

The version specifier uses an invalid operator '<=' is correct, but '=<' is not valid.

generic

中文

版本说明符使用了无效的运算符，'<=' 是正确的，但 '=<' 是无效的。

Workarounds

  1. 99% success 
    pip install 'package<=1.0.0'
  2. 90% success 
    pip install 'package~=1.0.0'
  3. 85% success 
    Refer to the packaging documentation.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Quoting does not fix the invalid operator.

  2. 95% fail

    Newer pip still enforces valid operators.

  3. 95% fail

    Force reinstall does not bypass parsing.
