我知道沒有安裝 python，所以我嘗試運行 python 命令

python
zsh: command not found: python

當我運行 python3 時它運行良好但是我使用 pyenv 安裝了 python3，它是使用 homebrew 安裝的

我知道沒有添加路徑，這就是我的 ~/.zshrc 檔案的樣子

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
source ~/.nvm/nvm.sh


export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

如何使 python 命令作業？花了將近 12 個小時，還沒有解決這個問題。

我試過的

brew install python@2

它說

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

更新 1 我做了評論中@ElapsedSoul 所寫的，但現在它給出了一個新錯誤。這一定是 Python 2 不兼容錯誤。不幸的是， brew install python@2 也不起作用，該怎么辦？

uj5u.com熱心網友回復：

匯入系統；列印“%s.%s.%s”

如果我見過一些舊的 Python 2 表示法，那是一些很好的表示法 :)

正如@ElapsedSoul 提到的。macOS 12.3 移除了多年來默認提供的 Python 2。因此，如果您需要 Python 2，我個人建議其他人不要升級到 12.3，直到找到替代解決方案。

一些可能的替代方案包括：

選項 0：通過 Homebrew 重新安裝 Python 2

不幸的是，Homebrew 很久以前就擺脫了 Python 2。然而，有一些解決方法可以嘗試讓它作業：How to reinstall python@2 from Homebrew? .

選項 1：使用 pyenv

我沒有測驗過這個，所以它可能不起作用。但如果是這樣，這可能是滿足您需求的最佳解決方案。從以下：

brew install pyenv
pyenv install 2.7.18
pyenv global 2.7.18

選項 2：使用另一個包管理器

例如，MacPorts仍然有 Python 2 可用。這也會將其添加到 PATH：

sudo port install python27

我確信還有其他提供 Python 2.7 的 macOS 包管理器。
