1. 手动方法：
需要按如下步骤卸载node + npm ：
- 从
/usr/local/lib目录下删除全部node和node_modules - 之后，从
/usr/local/include目录删除全部node和node_modules - 从
/usr/local/bin目录删除node,node-debug和node-gyp - 从
home路径删除.npmrc,.npm,.node-gyp,.node_repl_history - 从

sudo rm -rf /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node.1 /usr/local/lib/dtrace/node.d
sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp
2. Homebrew 和 nvm 方法 ：
如果是通过$ brew install node 方式在 Mac 上安装Nodejs ， 可通过如下方式：
#unintall
brew uninstall node;
brew cleanup;
rm -f /usr/local/bin/npm /usr/local/lib/dtrace/node.d;
rm -rf ~/.npm;
#install
brew install node;
which node
export NODE_PATH='/usr/local/lib/node_modules'
