$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zprofile
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zprofile
$ echo 'eval "$(pyenv init --path)"' >> ~/.zprofile
$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.profile
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.profile
$ echo 'eval "$(pyenv init --path)"' >> ~/.profile
$ echo 'eval "$(pyenv init -)"' >> ~/.zshrc

方法2：直接写入文件
# pyenv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
# pyenv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
# pyenv
eval "$(pyenv init -)"
