# For bash:
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
# For Ubuntu Desktop:
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
# For Zsh:
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
# For Fish shell:
set -Ux PYENV_ROOT $HOME/.pyenv
set -Ux fish_user_paths $PYENV_ROOT/bin $fish_user_paths

- 将
pyenv init添加到shell中以启用shims和autocompletion功能。请确保将eval "$(pyenv init -)"放在shell配置文件的末尾，因为它在初始化期间会操纵PATH。

echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.
fish note: Use pyenv init - | source instead of eval (pyenv init -).
Ubuntu and Fedora note: Modify your ~/.bashrc file instead of ~/.bash_profile.
- 刷新shell
- 安装编译环境
Install Python build dependencies
