“npm安装-g npm@latest”损坏了我的npm安装-Windows 8.1

Question

上个月，我安装了node 10.16.3 LTS，因为它没有最新的npm版本，所以我使用以下官方指南对其进行了更新：https://docs.npmjs.com/try-the-lates-stable-version-of-npm（选项2）：

1. 删除了%programfiles%\nodejs\npm和%programfiles%\nodejs\npm.cmd
2. 将'npmrc'文件从%programfiles%\nodejs\node_modules\npm移动到%appdata%\npm\nde_modules\npm

有什么方法可以在不重新安装整个Node.js的情况下修复这样损坏的npm安装吗？
谢谢
