我想重新安装node和npm。 为此，在删除旧软件后，我做了：
brew install node
但是最后我收到了以下消息：
Warning: The post-install step did not complete successfully
You can try again using `brew postinstall node`
然后，我不断得到这个：
$ brew postinstall node
==> Postinstalling node
Warning: The post-install step did not complete successfully
You can try again using `brew postinstall node`
以前有没有人经历过？
