<>一、删除python所在环境
你需要删除的东西有三,一是Library中的python(即环境变量),二是Application中的python,三是清除指向python的链接。故步骤分为如下三步:
## --删除frameworks下python-- cd /Library/Frameworks/Python.framework/Versions #
一般你的多种版本的python的环境都在这 sudo rm -rf ./3.x # (无提示地强制递归删除文件)删除当前文件夹下的3.x python环境
## --删除application下python-- sudo rm -rf /Applications/Python 3.x # 删除 ##
--删除指向python的链接-- cd /usr/local/bin/ ls -l /usr/local/bin | grep
‘/Library/Frameworks/Python.framework/Versions/3.7’# 查看链接 brew prune # 清除链接和目录
<>二、检查python是否已删除干净
使用where命令进行检查
whereis python
若只显示python2.7(系统自带的)则已删除完毕。
<>三、mac的环境变量在何处
用户设置的mac的环境变量在如下目录
vim ~/.bash_profile # 其中/是指根目录,~是指/Users/YourMacUserName
