1、遇到的问题

在安装vue时报下面的错误：

C:\Users\nxg>npm install -g @vue/cli
npm ERR! code EPERM
npm ERR! syscall open
npm ERR! path D:\Program Files\nodejs\node_cache\_cacache\tmp\bf1f8302
npm ERR! errno EPERM
npm ERR! FetchError: Invalid response body while trying to fetch https://registry.npmjs.org/@vue%2fcli: EPERM: operation not permitted, open 'D:\Program Files\nodejs\node_cache\_cacache\tmp\bf1f8302'

2、解决方法

方法1：
需要删除npmrc文件。

强调：不是nodejs安装目录npm模块下的那个npmrc文件

而是在C:\Users{账户}\下的.npmrc文件…
注意：这个文件默认是被隐藏，一定要选择将隐藏取消掉

需要删除隐藏文件

方法2：

或者直接用命令清理就行，控制台输入：

npm cache clean --force’

当删除之后，我们再去运行，就可以看到，我们的简单粗暴方式是很有效果的

注意在安装Vue时，也会报错，

npm install -g @vue/cli

解决办法是：使用管理员运行cmd，可以解决，如果还不能解决，就删除
把node.js安装时的目录下的package-lock.json文件删掉，分别是

D:\Program Files\nodejs\node_modules\npm\docs\package-lock.json和D:\Program Files\nodejs\node_modules\npm\node_modules\npm-normalize-package-bin\package-lock.json

具体报错如下：
