反应页面空白，没有错误

如何解决反应页面空白，没有错误

我的 React 应用程序只显示一页的空白页。此页面适用于我的本地主机。但是，当我部署时，我似乎只得到一个空白页面，控制台日志、网络等中没有错误......

我的第一篇文章，感谢您的帮助。我将在下面发布详细信息。

Register/Complete 是有问题的路由。

App.js

  <ToastContainer />
<Switch>
  <Route exact path="/" component={Home} />
  <Route path="/login" component={Login} />
    <Route exact path="/register" component={Register} />
    **<Route path="/register/complete" component={RegisterComplete} />**
    <Route path="/forgot/password" component={ForgotPassword} />
    <Route exact path="/score" component={Score} />
    <Route exact path="/marketing" component={Marketing} />
    <Route path="/edit" component={Edit} />
    <Route path="/dashboard" component={Dashboard} />
    <Route path="/assistant" component={EAHome} />

    
    <Route exact path="/private" component={EAPrivate} />
    <Route path="/private/v5" component={EAPrivateTwo} />
    <Route path="/private/accidents" component={EAPrivateThree} />
     <Route path="/private/service" component={EAPrivateFour} />
      <Route path="/private/repairs" component={EAPrivateFive} />
      <Route path="/private/warrenty" component={EAPrivateSix} />



    <Route exact path="/dealer" component={EADealer} />
    <Route exact path="/dealer/damage" component={EADealerTwo} />
    <Route path="/dealer/work" component={EADealerThree} />
    <Route path="/dealer/repair" component={EADealerFour} />
    <Route path="/dealer/warrenty" component={EADealerFive} />
    <Route path="/dealer/viewing" component={EADealerSix} />

    <Route path="/checkout" component={Full} />
    <Route path="/vdi-check" component={Vdi} />



    <Route path="/password" component={Password} />
    <Route path="/shortlist" component={Shortlist} />
    
  </Switch>
