Ubuntu - 如何在Python 3.3而不是Python 2.7上安装Python模块(BeautifulSoup)？

Question

我有这个代码(用BS4文档编写):

  from bs4 import BeautifulSoup

当我运行脚本(使用python3)时,我收到错误:

  ImportError: No module named 'bs4'

所以安装BeatifulSoup:

  sudo pip install BeatifulSoup4

但是当我再次尝试运行脚本时,我得到了同样的错误.确实BS4安装在:

  BeautifulSoup4 in /usr/local/lib/python2.7/dist-packages

但我想安装并使用它与python3.3(因为有其他模块不使用python2.7).

我尝试过:

  virtualenv --python=/usr/bin/python2.7 /usr/bin/python3.3

然后再次安装BS4,但没有解决.

任何线索？提前致谢

Answer 1

Ubuntu已经打包了beautifulsoup.我通过运行apt-cache搜索找到了它

$ apt-cache search beautifulsoup

我看到它在结果中同时具有2.7和3.3版本.您可以通过安装python3-bs4获得3.3版本

$ sudo apt-get install python3-bs4

Answer 2

使用pip3

sudo pip3 install BeautifulSoup4

如果您无法运行pip3,请使用以下命令安装它:

sudo apt-get install python3-setuptools
sudo easy_install3 pip 


xxx@Ubuntu14:~/Desktop$ sudo pip3 install BeautifulSoup4
