解决办法:

1. 删除/usr/local/lib中的所有node和node_modules
2. 删除/usr/local/lib中的所有node和node_modules的文件夹
3. 如果是从brew安装的, 运行brew uninstall node
4. 检查~/中所有的local, lib或者include文件夹, 删除里面所有node和node_modules
5. 在/usr/local/bin中, 删除所有node的可执行文件
6. 最后运行以下代码:

sudo rm /usr/local/bin/npm
sudo rm /usr/local/share/man/man1/node.1
sudo rm /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm /opt/local/bin/node
sudo rm /opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules

估计是你的node.js
$ brew update
$ brew uninstall node
$ brew install node
