Error: Cannot find module '@/views/user/index'
    at webpackEmptyContext (index.js:39)
    at permission.js:61

原来写法

export const loadView = (view) => {
   return () => import(`@/views/${view}`)
};

改为

export const loadView = (view) => {
    return (resolve) => require([`@/views/${view}`], resolve)
};

原因：webpack版本问题，webpack4中动态import不支持变量方式

该修改对于生产环境无影响，只在开发环境有问题
