升级

$ brew update
$ brew upgrade node

安装

# download and install Node.js
brew install node@20
# verifies the right Node.js version is in the environment
node -v # should print `v20.14.0`
# verifies the right NPM version is in the environment
npm -v # should print `10.7.0`

电脑上的版本太老了。删除重新下载安装
https://nodejs.org/en/download/prebuilt-installer 由于使用安装包的形式安装的，所以网上的卸载命令不起作用。
直接通过命令删除:

#删除 Node、npm
jimmy@MacBook-Pro npm % sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man/*/node.*}

# 验证
jimmy@MacBook-Pro npm % node -v
zsh: command not found: node
jimmy@MacBook-Pro npm % npm -v
zsh: command not found: npm
jimmy@MacBook-Pro npm %

重新安装

安装后验证

jimmy@MacBook-Pro npm % node -v
v20.14.0
jimmy@MacBook-Pro npm % npm -v
