为什么我的编辑（PHPSorm）说我不需要"等待"？它工作正常...
下面是代码：

export const fetchBoards = (): AppThunk =>
  async function (dispatch): Promise<void> {
    try {
      const { boards }: { boards: IBoardItem[] } = await api.get('/board');
      dispatch({ type: 'UPDATE_BOARDS', payload: boards });
      window.console.log('Success');
    } catch (e) {
      window.console.error(e);
      dispatch({ type: 'ERROR', payload: e });
    }
  };
export const addBoard = (board: { title: string }): AppThunk =>
  async function (dispatch): Promise<void> {
    try {
      const res = await api.post('/board', board);
      window.console.log(res);

      window.console.log('Before');
      await dispatch(fetchBoards()); // 'await' has no effect on the type of this expression
      window.console.log('After');
    } catch (e) {
      window.console.error(e);
      const res = dispatch({ type: 'ERROR', payload: e });
    }
  };
