我在使用react native的Camera模組的時候，出現了 LOG error: [Error: MEDIA_LIBRARY permission is required to do this operation.]的訊息，上網查到的方法也都沒法改善
程式碼如下:
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';
import React,{useState,useEffect,useRef} from 'react';
import { SafeAreaView,TouchableOpacity,Modal,Image,Alert } from 'react-native';
import { Camera } from 'expo-camera';
import { CameraType } from 'expo-camera';
import * as Location from 'expo-location';
import { FontAwesome,Ionicons } from '@expo/vector-icons';

import * as MediaLibrary from 'expo-media-library';

import * as Permissions from 'expo-permissions';

export default function App() {
const camRef=useRef(null);
const [type,setType]=useState(Camera.Constants.Type.back);
const [hasPermission,setHasPermission]=useState(null);
const[cpaturePic,setCpaturePic]=useState(null);
const [open,setOpen]=useState(null);

// 拍照
const takePicture=async()=>{
if(camRef){
const data=await camRef.current.takePictureAsync();
// console.log(data);
setCpaturePic(data.uri);
setOpen(true);
}
}

// 儲存照片
const savePicture=async()=>{
const asset=MediaLibrary.createAssetAsync(cpaturePic)
.then(()=>{
alert('照片存檔成功!')
setOpen(false)
}).catch((e)=>{
console.log('error:',e)
})
}

useEffect(() => {
(async () => {
const { status } = await Camera.requestCameraPermissionsAsync();
setHasPermission(status === "granted")
})();

(async () => {
  // const { status } = await Permissions.askAsync(Permissions.MEDIA_LIBRARY)
  const { status } = await Location.requestForegroundPermissionsAsync();
  console.log("status= ", status)
  setHasPermission(status === "granted")

})();

}, [])

if (hasPermission===null){
return
}
else if (hasPermission===false){
return 沒有照相機的使用權限!!!
}
