How to install python3 version of package via pip on Ubuntu?

I came across this and fixed this without needing the likes of wget or virtualenvs (assuming Ubuntu 12.04):

1. Install package python3-setuptools: run sudo aptitude install python3-setuptools, this will give you the command easy_install3.
2. Install pip using Python 3's setuptools: run sudo easy_install3 pip, this will give you the command pip-3.2 like kev's solution.
3. Install your PyPI packages: run sudo pip-3.2 install  (installing python packages into your base system requires root, of course).
4. …
5. Profit!

在Ubuntu中安装Python3

首先，通过命令行安装Python3.2，只需要在终端中通过命令行安装即可：

一路yes。

因为Ubuntu很多底层采用的是Python2.*，Python3和Python2是互相不兼容的，所以此时不能卸载Python2，需要将默认Python的指向Python3。

刚才的Python3是被默认安装带usr/local/lib/python3.2目录中，如下

首先，删除usr/bin/目录下的默认python link文件。

然后打开终端输入如下命令行，建立新的连接关系

成功

然后测试一下python版本是否正确

命令行输入 python 即可
