未处理的承诺拒绝：ReferenceError：找不到变量：setPosts

Question

将图像和数据上传到 firebase 并且它的回调很好。 但是在 promise 函数中，我得到了 Can't find variable : setPosts 的错误，它是由 Actions on Redux 定义的 这里

还有代码

// For Media
  const onPresslaunchCameraMedia = async () => {
    let result = await ImagePicker.launchCameraAsync({
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
      quality: 1,
    });
    if (!result.cancelled) {
      console.log("============ Media Uploaded By Photo =============")
      console.log(result.uri)
      await setMediaData({...mediaData, country : userData.country})
      await uploadMedia(mediaData, result.uri)
      dispatch(addPost(mediaData));
      navigation.dispatch(StackActions.replace('Home'));
    }
  };

使用 expo-cli 启动 react-native 应用
