无法导入setuptools

Posted 2021-04-20

我什么都没做，一切都坏了。

aviv$ python3 -c 'import setuptools'
Traceback (most recent call last):
  File "/usr/lib/python3.5/pkgutil.py", line 407, in get_importer
importer = sys.path_importer_cache[path_item]
KeyError: ''

这意味着点子被破坏并且气流被破坏。一切都被打破。请帮忙。

编辑：有人建议这是这个问题的重复：Python 3: ImportError "No Module named Setuptools"。我正在做一个不同的事情，并得到一个不同于该问题的错误，我也删除并重新安装了python3-setuptools与最新版本。仍然得到同样的错误。

编辑2：完全追溯：

During handling of the above exception, another exception occurred:

答案

找到了答案 - 这真的很愚蠢。

我试图从一个不再存在的目录运行所有内容。 os.getcwd()本身就错了。更改目录，再次运行，现在可以使用。
