我想从我的expo react原生应用程序实现本地通知。当我运行调度通知时,它抛出_expoModulesCore.uuidv4不是函数错误。
这是我的代码

包.json

字符串

通知.js文件

import Constants from "expo-constants";
import * as Notifications from "expo-notifications";
import React, { useState, useEffect, useRef } from "react";
import {  Platform } from "react-native";

Notifications.setNotificationHandler({
  handleNotification: async () => ({
    shouldShowAlert: true,
    shouldPlaySound: true,
    shouldSetBadge: true,
  }),
});

export default function Notification() {
  const [expoPushToken, setExpoPushToken] = useState("");  
  const [notification, setNotification] = useState(false);
  const notificationListener = useRef();
  const responseListener = useRef();

  useEffect(() => {
    registerForPushNotificationsAsync().then((token) =>
      setExpoPushToken(token)
    );

    notificationListener.current =
      Notifications.addNotificationReceivedListener((notification) => {
        setNotification(notification);
      });

    responseListener.current =
      Notifications.addNotificationResponseReceivedListener((response) => {
        console.log(response);
      });

    return () => {
      Notifications.removeNotificationSubscription(
        notificationListener.current
      );
      Notifications.removeNotificationSubscription(responseListener.current);
    };
  }, []);

  return (
    null
  );
}

export async function schedulePushNotification(
  title,
  body
) {
  const id = await Notifications.scheduleNotificationAsync({
    content: {
      title: title,
      body: body,
      // sound: 'default',
    },
    trigger: null
  });
  console.log("notif id on scheduling",id)
  return id;
}

async function registerForPushNotificationsAsync() {
  let token;
  if (Constants.isDevice) {
    const { status: existingStatus } =
      await Notifications.getPermissionsAsync();
    let finalStatus = existingStatus;
    if (existingStatus !== "granted") {
      const { status } = await Notifications.requestPermissionsAsync();
      finalStatus = status;
    }
    if (finalStatus !== "granted") {
      alert("Failed to get push token for push notification!");
      return;
    }
    token = (await Notifications.getExpoPushTokenAsync()).data;
    console.log(token);
  } else {
    alert("Must use physical device for Push Notifications");
  }

  if (Platform.OS === "android") {
    Notifications.setNotificationChannelAsync("default", {
      name: "default",
      importance: Notifications.AndroidImportance.MAX,
      vibrationPattern: [0, 250, 250, 250],
      sound: true,
      lightColor: "#FF231F7C",
      lockscreenVisibility: Notifications.AndroidNotificationVisibility.PUBLIC,
      bypassDnd: true,
    });
  }

  return token;
}

export async function cancelNotification(notifId){
  await Notifications.cancelScheduledNotificationAsync(notifId);
}

我也将其称为App.js

Notifications.setNotificationHandler({
  handleNotification: async () => ({
    shouldShowAlert: true,
    shouldPlaySound: true,
    shouldSetBadge: true,
  }),
});

可能是您项目的某些expo包丢失了,而这些包是运行Expo-notifications包所必需的。
我通过运行这个命令修复了这个问题:

expo install --fix
