nvm下升级npm版本

1 3445 error path C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\npm.cmd
2 3446 error Refusing to delete C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\npm.cmd: is outside C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\node_modules\npm and not a link
3 3447 error File exists: C:\Users\xxx\AppData\Roaming\nvm\v12.18.3\npm.cmd
4 3448 error Remove the existing file and try again, or run npm
5 3449 error with --force to overwrite files recklessly.
6 3450 verbose exit [ 1, true ]

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

// 2
node 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
