卸载node 依次在终端执行下面的脚本
sudo npm uninstall npm -g sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.* sudo rm -rf /usr/local/include/node /Users/$USER/.npm sudo rm /usr/local/bin/node sudo rm /usr/local/share/man/man1/node.1 sudo rm /usr/local/lib/dtrace/node.d最后验证一下
node //command not found npm //command not found大功搞成，恭喜你，卸载完了。
