};

export function getNowChannellist$ ($state: Observable<EchoesState>): Observable<NowChannellistInterface> {
  return $state.select(state => state.nowChannellist);
};

我得到的错误是:

Store 没有提供程序！

No provider for Store!

推荐答案

我知道这个问题似乎已经死了，但是对于信息，provideStore 函数不再存在，你应该做

I know this question seems dead, but for info, the provideStore function doesn't exist anymore, you should do

StoreModule.forRoot(/*your reducers here*/)

这篇关于Store 没有提供者！注射错误Error的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
