site.py: AttributeError: 在 PyCharm 中运行任何 python 文件时，'module' 对象没有属性 'ModuleType'

Question

我曾经使用nltkPyCharm 在 Python 3.4 上解析英语。当我运行我的文件时，我收到以下错误：

Error processing line 1 of /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/zope.interface-4.1.3-py3.4-nspkg.pth:

  Traceback (most recent call last):
    File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site.py", line 167, in addpackage

    File "<string>", line 1, in <module>
  AttributeError: 'module' object has no attribute 'ModuleType'

    _PopenSelector = selectors.SelectSelector
AttributeError: 'module' object has no attribute 'SelectSelector'

经过一番修补，我发现运行一个空文件给了我以下错误：

Error processing line 1 of /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/zope.interface-4.1.3-py3.4-nspkg.pth:

调试一个空文件让我：

我在 OS X 上使用 PyCharm 5.04 专业版。我认为这与我的编辑器有关，但我不确定。

Answer 1

types.py在您的当前目录中有一个名为的文件。

此文件隐藏types作为标准库一部分的模块。该nltk程序（非常）间接地尝试导入types，获取缺少ModuleType属性的模块，从而导致ImportError永远不会被捕获并产生该回溯。
