import Signup from './Signup'
import Home from './Home'
import EditProfile from './Editprofile'
import Payments from './Payments'
import { createDrawerNavigator } from 'react-navigation-drawer';


const MyDrawerNavigator = createDrawerNavigator({
  signup: {
    screen: Signup,},home: {
    screen: Home,editprofile:{

    screen:EditProfile
  },payments:{
    screen:Payments
  }
},{
  initialRouteName: 'signup',contentOptions: {
    activeTintColor: '#e91e63',});

const App = createAppContainer(MyDrawerNavigator);
export default App;

在我的react-navigation应用程序中，我无法导航按钮（三行按钮），但是我已正确安装并正确链接了所有依赖项
