python 环境切换
参考自:https://blog.csdn.net/Tyro_java/article/details/78510301
用的homebrew,BerkeleyCS61B课堂老师推荐https://sp19.datastructur.es/#cal
1.打开文件(空的就直接写)
vi ~/.bash_profile
2.修改内容为
alias python2="/usr/bin/python"
alias python3="/usr/local/bin/python3"
alias python=python3
3.这个一定要做(生效用的)
source ~/.bash_profile
ps:切换回去2的话
alias python2="/usr/bin/python"
alias python3="/usr/local/bin/python3"
alias python=python2
