Mac默认Python路径更改 [英] Mac Default Python Path Change

问题描述

我有一台Mac，碰巧到处都安装了许多不同风格的Python.

Hi I have a Mac and happen to have many different flavors of Python installed everywhere.

现在，当我在终端中打开python时，输入

right now when I opened up python in terminal, type in

which python

返回结果是:

//anaconda/bin/python

我想知道如何将默认python更改为我喜欢的python，所以下次我这样做时:

I am wondering what should I do to change the default python to a python that I like, so next time when I do:

which python

路径应为:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

谢谢！

推荐答案

which命令使用$PATH中列出的目录搜索命令的首次出现.如果要列出可执行文件的所有实例，请使用-a选项.

which command uses the directories listed in $PATH to search for the first occurrence of a command. If you want to list all instances of executables, use -a option.

which python2.7

输出:

/usr/bin/python2.7

这将显示指向/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

使用符号解析链接

readlink $(which python2.7)  

输出:

../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
