将我的React Native应用程序更新为React Native 0.59之后，在尝试以调试模式（react-native run-android）运行我的应用程序或生成软件包并安装到设备中后，我开始遇到问题。

以下是有关我的问题的信息：

    }
}

此错误在我的Metro-bundler加载100％之后发生（并且在Bundle Console屏幕上没有发生错误）。

感谢所有提供帮助的人！

该错误是因为您忘记在android中安装某些模块，所以请检查MainApplication.java并检查是否导入了所有软件包，以及是否将其添加到ReactPackage列表中。

答案 1 :(得分：1)

在我的情况下，问题出在react-native-device-info。

在您的app / build.gradle依赖项中尝试以下操作：

dependencies {
   ...
   implementation(project(':react-native-device-info')) {
      exclude group: 'com.google.android.gms'
   }
}

对我有用。

答案 2 :(得分：0)

这真是个笑话！！！实施此lib非常困难，但是4小时后...

build.gradle项目级别 

 dependencies {
            classpath 'com.android.tools.build:gradle:3.3.1'
            classpath 'com.google.gms:google-services:3.2.1'
        }

build.gradle应用程序级别 

  dependencies {
        // FIREBASE \\
        implementation 'com.google.firebase:firebase-database:11.4.2'
        implementation 'com.google.firebase:firebase-ads:11.4.2'
        implementation 'com.google.firebase:firebase-auth:11.4.2'
        implementation 'com.google.firebase:firebase-messaging:11.4.2'
        implementation  'com.google.firebase:firebase-core:11.4.2'
        // END \\
        implementation fileTree(dir: "libs", include: ["*.jar"])
        implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
        implementation "com.facebook.react:react-native:+"  // From node_modules
    }

然后最后将樱桃放到顶部：

**MainApplication.java**

     @Override
        protected List<ReactPackage> getPackages() {
          return Arrays.<ReactPackage>asList(
              new MainReactPackage(),
                new RNFirebasePackage(),
                  new RNFirebaseDatabasePackage(),
                  new RNFirebaseAnalyticsPackage(),
                  new RNFirebaseAdMobPackage(),
                  new RNFirebaseAuthPackage()
          );
        }

现在您可以使用 react-native-firebase 欢呼。...-.- 

import firebase from 'react-native-firebase';
firebase.analytics().logEvent('i_should_just_give_up_in_life');

希望这可以节省您的时间
