npm run build不显示任何内容-react js

Question

我想使用npm run build构建项目 和 当我构建项目时，所有文件均正确构建 并加载了CSS文件，图标，清单，js文件。

但是我的 js文件没有显示任何内容。

我正在使用 BrowserRouter

我不使用webpack

这是我的路线文件：

import React , { Component } from 'react';
import OnePage from './OnePage/OnePage';
import Blog from './OnePage/Blog/Blog';
import Blogs from './OnePage/Blogs/Blogs';
import Home from './WebApp/Routes/Home';
import Register from './WebApp/Routes/Register/Register';
import Buy from './WebApp/Routes/Buy/Buy';
import Profile from './WebApp/Routes/Profile/Profile';
import Support from './WebApp/Routes/Support/Support';
import Search from './WebApp/Routes/Search/Search';
import SearchCategories from './WebApp/Routes/Search/SearchCategories';
import Users from './WebApp/Routes/Users/Users';
import Suggestion from './WebApp/Routes/Suggestion/Suggestion';

import './../public/appStyle.css';
import { Route, BrowserRouter as Router } from 'react-router-dom';

export default class App extends Component {
  render(){
    return(
      <Router>
          <div>
            <Route exact path="/" component={OnePage}/>
            <Route exact path="/app/" component={Home}/>
            <Route exact path="/blog/:id" component={Blog}/>
            <Route path="/blogs" component={Blogs}/>
            <Route path="/app/register" component={Register}/>
            <Route path="/app/buy" component={Buy}/>
            <Route path="/app/profile/:id" component={Profile}/>
            <Route path="/app/support" component={Support}/>
            <Route path="/app/search" component={Search}/>
            <Route path="/app/categories/:id" component={SearchCategories}/>
            <Route path="/app/users" component={Users}/>
            <Route path="/app/suggestion" component={Suggestion}/>
          </div>
      </Router>
    );
  }
}

我该怎么办？
