根据自制程序安装程序本身的建议，请务必将此添加到您的.bashrc或.zshrc:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

参见:如何在Homebrew中使用python符号链接?

$ brew link --overwrite python
Linking /usr/local/Cellar/python/2.7.3... 28 symlinks created
$ which python
/usr/local/bin/python

只做:

brew install python
brew link python

在此之后，将其添加到bashrc或bash_profile中:

alias python='/usr/local/bin/python2'

享受吧!

祝福的人!我需要使用python 3.10版本来利用它的新功能。我在2022-07-03的解决方案如下。祝您编写python代码愉快!

» rm '/usr/local/bin/pip3.10'
» brew link python@3.10
» echo 'export PATH="/usr/local/opt/python@3.10/bin:$PATH"' >> ~/.zshrc
» python3

试着输入python3而不是python
