site.py：AttributeError：在PyCharm中運行任何python文件時，“模塊”對象沒有屬性“ ModuleType”

Question

我使用nltk在帶有PyCharm的Python 3.4上解析英語。 運行文件時，出現以下錯誤：

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):

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

稍作修改后，我發現運行一個空文件給我以下錯誤：

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:

  AttributeError: 'module' object has no attribute 'ModuleType'

調試一個空文件使我：

我在OS X上使用PyCharm 5.04 Professional Edition。我認為這與我的編輯器有關，但我不確定。

Answer 1

當前目錄中有一個名為types.py的文件。

此文件遮蓋了標准庫中的types模塊。 nltk程序（非常）間接嘗試導入types ，獲取缺少ModuleType屬性的模塊，從而導致ImportError ，該ImportError永遠不會被捕獲並產生該回溯。
