删除后如何重新安装 npm（但 ~./npm 仍然存在）？

Question

我运行遇到了一些问题，我运行 npm update -g 突然无法使用 npm（在此处提交问题：https://github.com/npm/npm/issues/12135）。

我尝试时得到以下结果：

$ npm
-bash: npm: command not found

我正在尝试恢复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 命令并得到以下结果：

$ curl https://npmjs.org/install.sh | sudo sh

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   193  100   193    0     0    422      0 --:--:-- --:--:-- --:--:--   422
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 移到行首时，我得到以下内容：

sudo curl -L https://www.npmjs.com/install.sh | sh

我检查了一下，~/.npm 文件夹仍然存在并且有它的内容，/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？

是你没有完全卸载npm造成的

尝试使用 rm -rf 删除旧文件夹，然后安装 npm。
