Root Cause

The specifier string contains a comma, which is not allowed; specifiers must be separated by spaces or passed as a list.

generic

中文

说明符字符串包含逗号，这是不允许的；说明符必须用空格分隔或作为列表传递。

Workarounds

  1. 95% success 
    SpecifierSet('>=1.0 <2.0')
  2. 90% success 
    SpecifierSet(['>=1.0', '<2.0'])

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Semicolons are also not valid separators in specifiers.

  2. 100% fail

    Quoting does not change the invalid syntax.
