直接npm install -g npm 报错 ，进入 C:\Users\xxx\AppData\Roaming\nvm\v12.18.3 直接
npm install npm
也一样报错
解决方案：
删除 C:\Users\xxx\AppData\Roaming\nvm\v12.18.3 目录下的 npm npm.cmd npx npx.cmd
然后重命名 C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\node_modules\ 下的npm文件夹（随便起个名 比如npm2）
// 1
cd C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\node_modules\npm2\bin
// 2node npm-cli.js i -g npm
然后再把npm2文件夹删掉
npm --version // 7.24.0
npm就更新完了。 ps：谨慎更新
