我在虚拟环境中安装了pip。它安装没有错误。这是激活venv后运行sudo pip install tweepy时得到的结果：

Requirement already satisfied (use --upgrade to upgrade): tweepy in  
/usr/local/lib/python2.7/dist-packages/tweepy-3.1.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): requests==2.4.3 in
/usr/local/lib/python2.7/dist-packages/requests-2.4.3-py2.7.egg (from tweepy)
Requirement already satisfied (use --upgrade to upgrade): requests-oauthlib==0.4.1 in 
/usr/local/lib/python2.7/dist-packages/requests_oauthlib-0.4.1-py2.7.egg (from tweepy)
Requirement already satisfied (use --upgrade to upgrade): six==1.7.3 in 
/usr/local/lib/python2.7/dist-packages/six-1.7.3-py2.7.egg (from tweepy)
Requirement already satisfied (use --upgrade to upgrade): oauthlib>=0.6.2 in 
/usr/local/lib/python2.7/dist-packages (from requests-oauthlib==0.4.1->tweepy)
Cleaning up...

所以，我敢肯定它是可行的。

当我运行样本tweepy脚本时，出现此错误：

./twitterStream.py
Traceback (most recent call last):
  File "./twitterStream.py", line 6, in <module>
    import tweepy
ImportError: No module named tweepy

我的脚本没有指定任何python解释器。为了确保它不在我现在在venv中指定解释器的地方。

有任何想法吗？

谢谢！

如果我使用“ pip install tweepy”，则会收到很多错误：
