undefined is not an object(evaluating '_ref.routes')

在新添一个tab后就报错，不知为何，google没搜到这个问题，
只在react-navigation看到这个issue1408
但还是不知道怎么解决，求助～

const HomeNavigator = TabNavigator(
  {
    Home: { screen: Home },
    Account: { screen: Account },
    Msg: { screen: Msg}, //新添一个tab
  },
  {
    tabBarComponent: TabBarBottom,
    tabBarPosition: 'bottom',
    swipeEnabled: false,
    animationEnabled: false,
    lazyLoad: true,
  },
)

I can't reproduce it, perhaps there is something wrong with your Msg component

+1 , same error, I just change TabNavigator options.

const HomeNavigator = TabNavigator(
  {
    Home: { screen: Home },
    Account: { screen: Account },
    Account2: { screen: Account },
  },
  {
    tabBarComponent: TabBarBottom,
    tabBarPosition: 'bottom',
    swipeEnabled: false,
    animationEnabled: false,
    lazyLoad: true,
  }
)

重新编译再次试了下，感觉是dva热加载的问题，不知道有没有解决方案

@vance-liu I don't think so, and I don't know how to fix it, I can't reproduce it, seems someone using react-navigation also be bothered by this problem, I don't think it's a issue from dva
