Question

我刚刚更新了pip和一些软件包，现在几乎在运行任何命令，例如show或list（-V有效）时，都会收到以下错误：

Exception:
Traceback (most recent call last):
  File "/Users/sterlingbutters/anaconda3/lib/python3.6/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2897, in _dep_map

    raise AttributeError(attr)

During handling of the above exception, another exception occurred:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/sterlingbutters/anaconda3/lib/python3.6/site-packages/-ytz-2018.5.dist-info/METADATA'

这仅仅是我的配置，还是存在已知的错误等？

关于如何解决它的任何想法？ -我不能说我曾经遇到过这个问题
