Reactjs Redux希望减速器是一个函数

Redux向我扔：

错误：预期减速器是一个函数。 排队

从索引：

从configureStore：

index.js

减根剂

import mockReducer from './mockReducer';

// export default { mockReducer };
export default mockReducer;

模拟减速器

找不到bug。第一次自己创建一个支持devtools插件的redux商店时，看起来你是在导出一个对象，而不是根减速机中的一个函数

减根剂

import mockReducer from './mockReducer';

// export default { mockReducer };
export default mockReducer;

谢谢成功了。如果我不能将多个还原程序包装到一个对象中，如何导出它们？@victor.ja我建议每个还原程序使用不同的文件。您可以导出默认的{mockReducer，secondReducer}，导入时从“./mockReducer”导入{mockReducer，secondReducer}

      store.replaceReducer(nextReducer);

  }

  return { store };
}

import mockReducer from './mockReducer';

export default { mockReducer };

export default function reducer(state = { hola: 'as' }, { type }) {
  switch (type) {
    default:
      return state;
  }
}

import mockReducer from './mockReducer';

// export default { mockReducer };
export default mockReducer;
