我正在我的项目中导入 nltk 库，但出现以下错误。如果有人有同样的错误，请帮助。

        Traceback (most recent call last):
  File "/home/nitai/Dropbox/thesis/PycharmProjects/auto_tagger2/tagger.py", line 4, in <module>
    import buildVocab
  File "/home/nitai/Dropbox/thesis/PycharmProjects/auto_tagger2/buildVocab.py", line 4, in <module>
    import nltk
  File "/usr/local/lib/python2.7/dist-packages/nltk/__init__.py", line 126, in <module>
    from nltk.stem import *
  File "/usr/local/lib/python2.7/dist-packages/nltk/stem/__init__.py", line 29, in <module>
    from nltk.stem.snowball import SnowballStemmer
  File "/usr/local/lib/python2.7/dist-packages/nltk/stem/snowball.py", line 25, in <module>
    from nltk.stem import porter
ImportError: cannot import name porter

我已经安装了所有 nltk 软件包。我不知道。
