第一步卸载npm和node

这里如果你的node是安装包安装的，不是通过brew安装的也没关系的，你可以直接跳过brew uninstall node

sudo npm uninstall npm -g
brew uninstall node

第二步删除node工作目录

sudo rm -rf /usr/local/lib/dtrace/node.d /usr/local/lib/node_modules /usr/local/bin/npm /usr/local/bin/nodemon /usr/local/bin/node /usr/local/include/node ~/.npm* ~/.node* /usr/local/share/man/*/node* /usr/local/share/man/*/npm*

执行完上面的命令之后你会发下如下目录都会被删掉

- `/usr/local/lib/dtrace/node.d
- `/usr/local/lib/node_modules`
- `/usr/local/bin/npm`
- `/usr/local/bin/nodemon`
- `/usr/local/bin/node`
- `/usr/local/include/node`
- `~/.npm*`
- `~/.node*`
- `/usr/local/share/man/*/node*`
- `/usr/local/share/man/*/npm*`
