react-native start --port = 8088 not wokring

$this用于当前的类,view是方法,但是是什么load.这是房产吗？

这个例子是正确的吗？

class super{

    public $property;

    public function superf1()
    {
        echo "hello";
    }
    public function col()
    {
        $this->superf1();
    }

    $this->property->super1();

}

我认为这是一个圣经问题。它工作正常，仅1天前，在npm安装后，我正面临此问题。

硬重装页面时出现“未找到”错误，但工作正常，我用build正常重装。这是我的路由器标签。我没有使用createBrowserHistory。是问题吗？

<Router basename={process.env.PUBLIC_URL}>
           <Switch >
          <div >
            <Navbar />
            <Route exact path="/" component={HomeComponent} />
            <Route exact path="/score/:id" component={ScoreComponent} />
            <Route exact path="/login" component={LoginComponent} />
            <Route exact path="/forgotPassword" component={ForgotPasswordComponent} />
          </div> 
          </Switch >
      </Router>
