在终端使用npm run dev 命令运行vue项目时报错npm ERR! code EPERM npm ERR! syscall opennpm ERR!

输入npm run dev 命令时出现：以下错误

npm ERR! code EPERM  
npm ERR! syscall open
npm ERR! path D:\dev\nodejs\node_cache\_cacache\tmp\5b622c44
npm ERR! errno -4048

1.在网上找解决办法修改了C:\Users{账户}\下的.npmrc文件，选择将隐藏取消掉发现运行还是报原来的错

原来

修改后

运行还是报错

2.后来发现是权限的问题

nodojs的文件中的模块操作权限不够

解决方案：

找到你安装node.js的文件夹

点击应用保存

再运行就没有错误了
