webstorm上导入了react项目，执行npm run start 之后就报错，

> cross-env APP_TYPE=site umi dev

fs.js:114
throw err;
^

看错误信息是要写某个文件时没有权限，这时根据路径过去看下是个隐藏文件，打开看一下只有一对“”，

网上能搜到的方法一般都是用管理员权限去运行“命令行”，这时候发现没用，

然后有的提到让修改整个项目文件夹的属性，给当前用户添加修改权限，也没用，

最后可以试下给这个.babel.7.2.2.development.json文件重命名一下，加个“_bak”后缀，然后再去webstorm中运行一下，

此时可以正常编译运行了，
