Javascript react redux导入reducer调度

我试图遵循react redux模板中的反例，但我似乎无法导出自己的setOwner减速机.

ownerSelector.tsx:

export  const ownerSlice = createSlice({
  name: 'owner',
  initialState,

  reducers:{
    setOwner: (state) => {    //Export this reducer
      let own = document.getElementById("OwnerSelector") as HTMLSelectElement
      state.id = parseInt(own!!.options[own.selectedIndex].value);
    }
  },
  extraReducers: (builder) => {}
})

export const selectOwner= (state: RootState) => state.selectedOwner.id;
export default ownerSlice.reducer;

我想在carForm.tsx中输入setOwner:

import {setOwner} from './ownerSelector'; // error here


    let submitHandler = (e: React.FormEvent<HTMLElement>) => {
        e.preventDefault();

        dispatch(setOwner())
        const formData = {
            car: {
                year: year,
                make: make,
                model: model,
                price: price,
                person_id: owner,
            }
        }
        dispatch(createCarAsync(formData));
        resetState();
    }

导入时的错误是:Module '"./ownerSelector"' has no exported member 'setOwner'. Did you mean to use 'import setOwner from "./ownerSelector"' instead?ts(2614)

我做错了什么？谢谢
