我对反应本土的事情有点新意，所以请原谅我可能犯了愚蠢的错误。
我在发布这里之前基本上尝试了所有我能找到的东西，现在我不确定这是不是我的结果（也就是我傻）或者由于最近的某些更新而导致的错误。
所以，我的问题是上面提到的错误消息，我在尝试构建应用程序时（通过使用react-native run-android或甚至使用gradlew clean）获得。我发布了下面的完整错误消息以及我的app / build.gradle，build.gradle和settings.gradle文件。
我按照“react-native init”创建的方式保留了所有文件，并且“只是”根据各自库的安装指南添加了我必须添加的命令。
由于最近Firebase SDK发生了变化，因此我不得不在gradle版本等方面进行相当多的更改。这就是为什么我想知道这个问题是否与此有关？！
哦，版本号：
"dependencies": {
"babel-core": "^6.26.3",
"eslint": "^4.19.1",
"fbjs": "^0.8.16",

"react-redux": "^5.0.7",
"redux": "^4.0.0",
"redux-logger": "^3.0.6",
"redux-thunk": "^2.2.0"
}
我安装了每个包装有纱线（yarn add react-native-vector-icons等）和npm（npm install，以及npm install react-native-vector-icons等），以确保它与任何一个都无关。在我之间我删除了整个node_modules文件夹。
react-native link也没有帮助。
它也不仅限于提到的react-native-vector-icons包：我将它从我的项目中完全删除，同样的错误只会弹出另一个包。
我感谢任何帮助和提示！
非常感谢你！

将google()移到顶部有时可以解决类似的问题。
您的代码中的示例修复程序
buildscript {
google()
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:3.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
mavenLocal()
jcenter()
maven {
url "$rootDir/../node_modules/react-native/android"
}
}
}
答案 1 :(得分：5)
您可以在项目的根文件夹
中运行以下命令1. You need to delete both ios,android and node module folder. Run the following commands
2. > npm install //to get the node module folder
3. > react-native upgrade //to get android and ios folder
4. > react-native link // for linking the libraries
5. > react-native run android/ios
答案 2 :(得分：5)
为什么我总是在论坛或Stackoverflow上询问后立即找到问题的答案？的xD
刚刚在this post中找到了解决方案：
显然，＆＃34; google-services＆＃34;我正在使用的版本。 降级
interventionViewModel.getExceptions().observe(this, exception ->{
if(exception instanceof QuantityOverflowException){
Toast.makeText(getActivity(), "No you just can't add more stock than there is available!", Toast.LENGTH_SHORT).show();
}
if(exception instanceof ScannedArticleNotFoundException){
Toast.makeText(getActivity(), "This article doesn't even exist! Get your shit together please!²", Toast.LENGTH_SHORT).show();
}
});
到
getActivity()在我的＆＃34; build.gradle＆＃34;文件达成了协议。
答案 3 :(得分：1)
我从@Prahbu开始，但在中间变了，所以我认为我会把我所做的作为不同的答案发布：
这是我所做的（同样在项目的根文件夹中）：
1. You need to delete both ios,android and node module folder. Afterwards, you can run the following commands
2. > npm install //to get the node module folder
3. > react-native-git-upgrade
您最终会偶然发现this error。在这种情况下，请删除.babelrc（保存其内容之后），例如，可以将其重命名为.babelrc2，并在完成后将生成的.babelrc替换为您的{}。
如果react-native-git-upgrade没有生成ios和android文件夹，请运行
react-native eject
根据原始答案，剩下的就是
4. > react-native link // for linking the libraries
5. > react-native run android/ios
答案 4 :(得分：0)
运行cd android && ./gradlew clean
