Question

我安装了NLTK软件包，我可以在Jupyter Notebook中导入NLTK，但不能在PyCharm中导入它。

>>> import nltk
>>> import sys
>>> print('\n'.join(sys.path))

在jupyter笔记本中：

/Users/morphy/anaconda3/lib/python36.zip
/Users/morphy/anaconda3/lib/python3.6
/Users/morphy/anaconda3/lib/python3.6/lib-dynload
/Users/morphy/anaconda3/lib/python3.6/site-packages
/Users/morphy/anaconda3/lib/python3.6/site-packages/aeosa
/Users/morphy/anaconda3/lib/python3.6/site-packages/IPython/extensions 
/Users/morphy/.ipython

但是在Pycharm：

SyntaxError: invalid syntax

当我导入其他软件包如numpy和sklearn时，也会发生同样的错误。

更新：已解决。

我在当前工作目录中创建了一个名为difflib.py的文件，因此当导入numpy时，它将调用此文件而不是它自己的库文件。

此问题与Numpy import throws AttributeError: 'module' object has no attribute 'core'

类似

无法在PyCharm中导入某些包
