builtins.TypeError: _findCaller() 需要 1 到 2 个位置参数，但 django 中给出了 3 个

Question

我有一个 django 的抓取项目。一切正常，但终端显示此错误：

builtins.TypeError：_findCaller() 接受 1 到 2 个位置参数，但给出了 3 个

这是什么错误？

我该如何处理？

这可能是与旧版本兼容的结果，根据..logging/__init__.py 设置中的文档_srcfile = None应避免引发TypeError

_srcfile 仅与 sys._getframe() 结合使用。为了提供与旧版本 Python 的兼容性，如果 _getframe() 不可用，请将 _srcfile 设置 为 None ；该值将阻止 调用 findCaller()。如果您想避免获取调用者信息的开销，即使 _getframe() 可用，您也可以这样做。

  if not hasattr(sys, '_getframe'):
     _srcfile = None
