1、安装npm
sudo apt update #更新 sudo apt --fix-broken install #修复 sudo apt upgrade -y #详细更新 sudo apt install -y nodejs npm #装npm，总共需要10分钟左右 node -v npm -v #确认否安装成功2、检查版本匹配
npm install -g @openai/codex这里可能会提示你需要node16版本以上，还有npm的权限问题
(base) user@user:~/software$ node -v npm -v v12.22.9 8.5.1 (base) user@user:~/software$ npm install -g @openai/codex npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: '@openai/codex@0.115.0', npm WARN EBADENGINE required: { node: '>=16' }, npm WARN EBADENGINE current: { node: 'v12.22.9', npm: '8.5.1' } npm WARN EBADENGINE } npm ERR! code EACCES npm ERR! syscall mkdir npm ERR! path /usr/local/lib/node_modules npm ERR! errno -13 npm ERR!

1）创建目录并下载 nvm 脚本
export NVM_DIR="$HOME/.nvm" mkdir -p "$NVM_DIR" curl -L https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/nvm.sh -o "$NVM_DIR/nvm.sh" curl -L https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/bash_completion -o "$NVM_DIR/bash_completion" chmod +x "$NVM_DIR/nvm.sh"2）写入~/.bashrc
cat >> ~/.bashrc <<'EOF' export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" EOFsource ~/.bashrc nvm -v
3）装新node
nvm install 20 nvm use 20 nvm alias default 20node -v npm -v which node which npm这里的which node和which npm最好都指向你家目录下的~/.nvm/...，而不是/usr/bin/node。这是为了避免继续用到系统自带的老版本。这个行为符合 nvm 的按用户、按 shell 管理版本的设计
3、安装codex
npm install -g @openai/codex npm i -g @openai/codex@latest然后enter登录GPT账号，无痕模式、换节点、更新这些方式都试试，解决因为接入地区无法登入的问题
ps：没有sudo权限时候可以如下安装部署：
# 1. 安装 nvm（用户目录，不需要 sudo） curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.6/install.sh | bash # 2. 重新加载 shell source ~/.bashrc # 如果你用的是 zsh，则： # source ~/.zshrc # 3. 安装 Node.js LTS nvm install --lts # 4. 检查 Node/npm node -v npm -v # 5. 安装 Codex CLI npm install -g @openai/codex # 6. 检查 Codex codex --version
