node.js - "npm install -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，所以我使用官方指南更新了它:https://docs.npmjs.com/try-the-latest-stable-version-of-npm (选项2):

1. 删除了 %ProgramFiles%\nodejs\npm 和 %ProgramFiles%\nodejs\npm.cmd
2. 已将“npmrc”文件从 %ProgramFiles%\nodejs\node_modules\npm 移至 %appdata%\npm\node_modules\npm

今天，在我安装“create-react-app”后，npm 向我显示消息，npm 的新次要版本已可用 6.11.3 -> 6.12.0，我可以更新它。
我运行了“npm install -g npm@latest”，但这只是给我带来了一堆错误:

C:\Users\Wladyslaw\AppData\Roaming\npm\npx -> C:\Users\Wladyslaw\AppData\Roaming\npm\node_modules\npm\bin\npx-cli.js

现在我什至无法运行“npm -v”，它以某种方式删除了我的 npm 文件夹并只向我显示此消息:

bash: /c/Users/Wladyslaw/AppData/Roaming/npm/npm: No such file or directory

有没有办法修复这种损坏的 npm 安装，而无需重新安装整个 Node.js？
谢谢
