如何在python3上安装第三方模块

Question

There are several versions of python on my mac OS X system. I just installed beautiful soup4 on python2.7.6, but how can I install the same module on the version 3.4.3?

Answer 1

From the BeautifulSoup Official Documentation :

Beautiful Soup 4 is published through PyPi, so if you can't install it with the system packager, you can install it with easy_install or pip. The package name is beautifulsoup4, and the same package works on Python 2 and Python 3.

 $ easy_install beautifulsoup4 $ pip install beautifulsoup4 

Answer 2

You should always use a virtualenv. For each project, install the requirements you need inside that project's own virtualenv.
