配置使用

如果anaconda的PATH没有添加到~/.bashrc文件中,那么每次使用之前,请在当前终端执行如下命令:

export PATH=$HOME/anaconda2/bin:$PATH

如果已经添加到~/.bashrc中,则每次启动终端后会自动调用该anaconda环境。

执行python

在当前终端执行“python”命令,得到:

Python 2.7.13 |Anaconda 4.4.0 (64-bit)| (default, Dec 20 2016, 23:09:15) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

进阶

如果我们同时安装的了anaconda2和anaconda3,那么可以在~/.bashrc中添加如下命令:

alias py2='export PATH=$HOME/anaconda2/bin:$PATH'
alias py3='export PATH=$HOME/anaconda2/bin:$PATH'

当想使用python2的时候,就输入py2;同理,输入py3。
