python - maya.parse 在某些日期失败（AttributeError：'NoneType' 对象没有属性'replace'）

问题描述

尝试解析某些 ISO 字符串日期时，maya.parse 函数会引发错误。

例子：

maya.parse("Mon, 02 Mar 2020 00:00:00 GMT")

工作示例：

maya.parse("Wed, 02 Sep 2020 00:00:00 GMT") <MayaDT epoch=1599004800.0>

maya.parse("Tue, 01 Sep 2020 00:00:00 GMT") <MayaDT epoch=1598918400.0>

  File "<stdin>", line 1, in <module>
  File "/Users/eanna/.local/share/virtualenvs/yo-_4WEwAWG/lib/python3.7/site-packages/maya/core.py", line 766, in parse
    dt = pendulum.parse(str(string), **options)
  File "/Users/eanna/.local/share/virtualenvs/yo-_4WEwAWG/lib/python3.7/site-packages/pendulum/parser.py", line 29, in parse
    return _parse(text, **options)

    return (dt.replace(tzinfo=None) - EPOCH).total_seconds()
