My problem was solved following @theWanderer4865 suggestions in the comments.

首先，我在执行的终端中卸载了通过brew:安装的节点版本:

First, I uninstalled the node version I had installed through brew: in the terminal I executed:

> brew cleanup
> brew uninstall node

第二，我通过运行删除了已安装的所有其他节点版本:

Second, I removed all other node versions I had installed by running:

> rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,n‌​ode*,man1/node*}

第三，使用 nvm 重新安装节点:

Third, install node again using nvm:

> nvm install node
