我在使用 rn-fetch-blob 访问 React Native 中的本地资源时遇到问题，这是我的目录结构：

我想从 App.js 访问文件 Female.png，这是我的脚本：

RNFetchBlob.fs.readFile('./female.png', 'base64')
    .then((data) => {
      console.log(data);
    })

我总是收到这个错误：

Possible Unhandled Promise Rejection (id: 14):

我在构建发布 React Native ios 时遇到问题，我尝试寻找许多示例，但全部失败。

这是错误消息：

  "_RCTSharedApplication", referenced from:

      -[momsindonesiaTests testRendersWelcomeScreen] in momsindonesiaTests.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不知道如何再次解决这个错误，请帮我解决这个问题。

谢谢。

我在 react native 中遇到问题，我不知道为什么在开发应用程序时突然出现这个问题，我尝试寻找一个示例但都失败了。

错误详情如下：

Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'LinkingManager' could not be found. Verify that a module by this name is registered in the native binary.

请任何人帮助我解决这个问题。

我必须要改变小图标推送通知Onesignal离子3个问题，我已经尝试了本教程https://documentation.onesignal.com/docs/customize-notification-icons，https://ionicframework.com/docs/native/ onesignal /和https://github.com/OneSignal/OneSignal-Cordova-SDK/issues/341#issuecomment-382648188，但是全部失败，我的推送通知中的小图标仍然默认为onesignal。

这是我的文件夹结构和脚本：

我的文件夹结构：

copy_android_notification_icons.js：

#!/usr/bin/env node

var fs = require('fs');
var path = require('path');

var rootDest = 'platforms/android/app/src/main/res';
var files = [{
    'icon_onesignal/res/drawable-hdpi/ic_stat_onesignal_default.png':
        path.join(rootDest, 'drawable-hdpi/ic_stat_onesignal_default.png')
}, {
    'icon_onesignal/res/drawable-mdpi/ic_stat_onesignal_default.png':
        path.join(rootDest, 'drawable-mdpi/ic_stat_onesignal_default.png')
}, {
    'icon_onesignal/res/drawable-xhdpi/ic_stat_onesignal_default.png':
        path.join(rootDest, 'drawable-xhdpi/ic_stat_onesignal_default.png')

  if (!fs.existsSync(pathAbsolute)) {
    fs.mkdirSync(pathAbsolute);
  }

  console.log('Folder ready ', pathAbsolute);

我在 React Native 中发现更新配置文件 firebase 的问题，我尝试查找示例但全部失败，也许您可​​以给我建议或者您可以更正我的脚本。

firebase.auth().createUserWithEmailAndPassword(this.state.email, this.state.password)
    .then(
      (user)=>{
        if(user){
          user.updateProfile({
            displayName: 'Frank S. Andrew'
          }).then((s)=> {
            this.props.navigation.navigate('Account');
          })
        }
    })
    .catch(function(error) {
      alert(error.message);
    });

我尝试遵循所有示例，在警报中显示消息“user.updateProfile 不是函数”。

请任何人帮助我如何在 React Native 中更新配置文件 (displayName) firebase。

谢谢。
