我遇到了一些问题：npm update -g我突然无法使用npm（在此提出问题：https://github.com/npm/npm/issues/12135）。
我尝试时会得到以下内容：
$ npm
-bash: npm: command not found
我尝试重新启动并运行，但我无法通过命令行安装它。我尝试使用在线列出的cURL命令并获得以下内容：
$ curl https://npmjs.org/install.sh | sudo sh

sh: line 1: html: No such file or directory
sh: line 2: syntax error near unexpected token `<'
'h: line 2: `<head><title>301 Moved Permanently</title></head>
当我将sudo移到线的前面时，我得到了以下内容：
sudo curl -L https://www.npmjs.com/install.sh | sh

我检查过，~/.npm文件夹仍然存在，并且有其内容，/usr/local/lib/node_modules/也是如此。这里发生了什么？我该如何解决这个问题？
