我已经尝试过的
brew install python@2上面写着
Warning: No available formula with the name "python@2". Did you mean ipython, bpython, jython or cython?
==> Searching for similarly named formulae...
These similarly named formulae were found:
ipython bpython jython cython
To install one of them, run (for example):
brew install ipython

Error: No formulae found in taps.更新1我做了@ElapsedSoul在评论中所写的内容，但现在出现了一个新的错误。这一定是Python 2不兼容的错误。不幸的是，做brew安装python@2也不起作用，怎么办？

输入sys；打印“%s.%s”
这是一些很好的Python 2表示法，如果我见过的话:)
正如@ElapsedSoul所提到的。macOS 12.3删除了这些年来默认出现的Python2。因此，如果您需要Python 2，在找到替代解决方案之前，我个人建议其他人不要升级到12.3。
一些可能的备选办法包括：
选项0:通过Homebrew重新安装Python 2
不幸的是，很久以前，自制软件摆脱了Python 2。然而，有一些解决办法可以尝试让它发挥作用：如何从自制软件中重新安装python@2？。
备选案文1:使用pyenv
我还没测试过这个，所以可能不起作用。但是如果是这样的话，这可能是满足您的需求的最佳解决方案。来自以下是
brew install pyenv
pyenv install 2.7.18
pyenv global 2.7.18选项2:使用另一个包管理器
例如，MacPorts仍然有Python2可用。这还会将其添加到PATH：
sudo port install python27我确信还有其他macOS包管理器也提供Python2.7。
