ubuntu/ Mac/Linux 升级 nodejs
一般使用 nvm 工具进行升级，适合多版本切换，开发首先。
步骤一：
安装 nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
或者
curl -o- https://gitee.com/mirrors/nvm/raw/v0.39.7/install.sh | bash
其中 0.39.7 版本根据实际情况跟换，
国内地址：https://gitee.com/mirrors/nvm  使用文档中的最新版本即可。
步骤二：
安装后需重启终端，或手动执行以下命令让 nvm 立即生效：
source
 ~/.bashrc# 若你的Ubuntu用zsh，执行：source ~/.zshrc
步骤三：
验证：
nvm -v
步骤4：
升级 / 安装 Node.js 版本
nvm ls-remote# 只看LTS长期支持版（推荐）nvm ls-remote --lts
安装指定的版本
# 安装22 LTS（生产首选）nvm install 22# 安装后自动设为全局默认版本nvm alias default 22
切换版本，使用已经有的版本
# 切换到22版本nvm use 22
步骤5：
验证nodejs版本
node -v && npm -v
