第一步设置代理

export https_proxy=http://127.0.0.1:7897 http_proxy=http://127.0.0.1:7897 all_proxy=socks5://127.0.0.1:7897

安装 brew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

安装版本管理器 nvm(node) pyenv(python)

brew install nvm
brew install pyenv

打开配置文件​

open ~/.zshrc

配置环境变量​

# nvm 环境变量
export NVM_DIR="$HOME/.nvm"
[ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && \. "/opt/homebrew/opt/nvm/nvm.sh"  # This loads nvm
[ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion
# 自动 use 已安装的 Node 版本（基于 .nvmrc 或 .node-version）
autoload -U add-zsh-hook
load-nvmrc() {
  local nvmrc_path="$(nvm_find_nvmrc)"
  if [ -n "$nvmrc_path" ]; then
    # 读取 .nvmrc 中的版本号并解析为具体版本 (如 v18.16.0)
    local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")")
    local current_node_version=$(nvm version)
    if [ "$nvmrc_node_version" = "N/A" ]; then
      # 版本未安装：执行安装
      nvm install
    elif [ "$nvmrc_node_version" != "$current_node_version" ]; then
      # 版本已安装但不匹配：静默切换
      nvm use --silent
    fi
  fi
}
add-zsh-hook precmd load-nvmrc

# python
export PYENV_ROOT="$HOME/.pyenv"
command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
alias python='python3'
alias pip='pip3'

重载配置​

source ~/.zshrc

安装​

# node
nvm install 25
nvm alias default 25
# python
pyenv install 3.11.9
pyenv global 3.11.9
