BeautifulSoup导入错误

Question

我正在尝试编写一个简单的本地python脚本来进行一些html解析.我安装了beautifulsoup4并使用它导入

from bs4 import BeautifulSoup

但我得到错误:

Traceback (most recent call last):
  File "scrape_descriptions.py", line 1, in <module>
    from bs4 import BeautifulSoup
ImportError: No module named 'bs4'

我尝试过各种方式安装BS4.首先,我做了

sudo pip install BeautifulSoup4

然后我尝试从网站上下载实际文件并运行

sudo python setup.py install

最后我试了一下

sudo su
easy_install BeautifulSoup4

所有这些操作似乎都已成功完成.但我仍然遇到这个错误.我已经搜索了其他帖子,但几乎所有帖子都只是安装说明,我已经完成了.

打字

pip freeze

显示bs4已安装但正在运行

$ python3 -i
>>> help('modules')

似乎没有列出bs4.

编辑1:运行sudo pip3 install BeautifulSoup给出了这个错误:

编辑2:解决了!pip3失败的原因是因为我正在使用

sudo pip3 install BeautifulSoup

代替

sudo pip3 install BeautifulSoup4

哪个有效.谢谢!
