1.查看python版本
|
1 2 3 4 5 6 |
Jiaheng:~ jiaheng$ which python /usr/bin/python Jiaheng:~ jiaheng$ which python3 /Library/Frameworks/Python.framework/Versions/3.8/bin/python3 Jiaheng:~ jiaheng$ which python3.8 /Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8 |
2.修改版本
修改用户根目录下的~/.bash_profile文件，在终端输入：
Jiaheng:~ jiaheng$ open ~/.bash_profile
在文件中新增一行：
alias python=”/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8″
添加完之后执行：
Jiaheng:~ jiaheng$ source ~/.bash_profile
验证：
Jiaheng:~ jiaheng$ python –version
