Python的安装路径

系统默认的Python环境：

/System/Library/Frameworks/Python.framework/Versions

 

本身安装的python环境在：

/Library/Frameworks/Python.framework/Versions

# Homebrew 
export PATH=/usr/local/bin:$PATH

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
# PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
PATH="/System/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

更改 ～/.bash_profile 文件的PATH 指向 python 版本的

source .bash_profile
