ImportError：没有名为bs4的模块

Question

我在OSX中使用pip安装了BeautifulSoup4，但我收到了这个错误：

dyn-72-33-214-45:craiglist mona$ python t1.py 
Traceback (most recent call last):
  File "t1.py", line 1, in <module>
    from bs4 import BeautifulSoup
ImportError: No module named bs4

知道怎么解决吗？

dyn-72-33-214-45:craiglist mona$ pip install BeautifulSoup4
....
Successfully installed BeautifulSoup4
Cleaning up...

Answer 1

我使用easy_install安装它，现在它正在运行。但首先您应该使用sudo su：

dyn-72-33-214-45:craiglist mona$ sudo su
sh-3.2# easy_install beautifulsoup4
