vue-cli4.5项目发布上线，页面空白，控制台404

Question

在本地正常,部署到线上之后页面空白，vue-cli为4.5版本，控制台Failed to load resource: the server responded with a status of 404 (Not Found)。请大佬帮忙看看

vue.config.js

module.exports = {
    // publicPath: process.env.NODE_ENV === 'production'
    // ? './'
    // : '/',
    // outputDir: 'dist',
    chainWebpack: config => {
        //发布模式
        config.when(process.env.NODE_ENV === 'production', config => {
            //entry找到默认的打包入口，调用clear则是删除默认的打包入口
            //add添加新的打包入口
            config.entry('app').clear().add('./src/main-prod.js')

            //使用externals设置排除项
            config.set('externals', {
                vue: 'Vue',
                'vue-router': 'VueRouter',
                axios: 'axios',
                lodash: '_',
                echarts: 'echarts',
                nprogress: 'NProgress',
                'vue-quill-editor': 'VueQuillEditor'
            })

            config.plugin('html').tap(args => {
                args[0].isProd = true
                return args
            })
        })

        //开发模式
        config.when(process.env.NODE_ENV === 'development', config => {
            config.entry('app').clear().add('./src/main-dev.js')

            config.plugin('html').tap(args => {
                args[0].isProd = false
                return args
            })
        })
    }
}

router.beforeEach((to, from, next) => {

  if (to.path == '/login') return next();//直接放行
  //获取token
  const tokenStr = window.sessionStorage.getItem('token');
  if (!tokenStr) return next('/login');//强制跳转
  next();

})
export default router

不知道你这个问题是否已经解决, 如果还没有解决的话:

• 请看👉 ：vue-cli3打包上线时遇到的坑（打包后页面空白、接口404、进入二级页面刷新404）

如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 以帮助更多的人 ^-^
