Ubuntu - How to install a Python module (BeautifulSoup) on Python 3.3 instead of Python 2.7?
提问by dragonmnl
I have this code (as written in BS4 documentaion):
我有这个代码（如 BS4 文档中所写）：
from bs4 import BeautifulSoup
When I run the script (using python3) I get the error:
当我运行脚本（使用 python3）时，出现错误：
ImportError: No module named 'bs4'
So installed BeatifulSoup by:
因此，通过以下方式安装了 BeatifulSoup：
sudo pip install BeatifulSoup4
But when I try to run the script again I get the same error. Indeed BS4 is installed in:
但是当我再次尝试运行脚本时，我得到了同样的错误。事实上 BS4 安装在：
BeautifulSoup4 in /usr/local/lib/python2.7/dist-packages
But I want to install and use it with python3.3 (as there are other module which are not working with python2.7).
但我想安装并与 python3.3 一起使用它（因为还有其他模块不适用于 python2.7）。
I tried with:
我试过：
virtualenv --python=/usr/bin/python2.7 /usr/bin/python3.3
and then install BS4 again, but nothing solved.
然后再次安装BS4，但没有解决。
Any clue? Thanks in advance
有什么线索吗？提前致谢

Ubuntu has beautifulsoup packaged. I found it by running apt-cache search
Ubuntu 已经打包了 beautifulsoup。我通过运行 apt-cache search 找到了它
$ apt-cache search beautifulsoup
I see it has both a 2.7 and 3.3 version in the results. You can get the 3.3 version by installing python3-bs4
我看到结果中有 2.7 和 3.3 版本。安装python3-bs4即可获得3.3版本
$ sudo apt-get install python3-bs4

Use pip3
使用 pip3
sudo pip3 install BeautifulSoup4
If you cannot run pip3 install it with the following:
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

I have often referenced the documentation link: https://docs.python.org/3/installing/
我经常引用文档链接：https: //docs.python.org/3/installing/
Some examples:
一些例子：
python2 -m pip install SomePackage # default Python 2
python2.7 -m pip install SomePackage # specifically Python 2.7
python3 -m pip install SomePackage # default Python 3
python3.4 -m pip install SomePackage # specifically Python 3.4

I had the same problem, but when I tried to "sudo apt-get install'python3-bs4" it said it was already installed. I ran my program with "python3 program.py" and it worked just fine.
我遇到了同样的问题，但是当我尝试“sudo apt-get install'python3-bs4”时，它说它已经安装了。我用“python3 program.py”运行了我的程序，它运行得很好。
