Question

我正在尝试使用facebook / react-native教程[https://github.com/facebook/react-native/tree/master/RNTester]安装RNTester，但是当我执行“ ./gradlew：RNTester：android：app：installDebug”时，显示一个错误。 / p>

This is for the Ubuntu 19.04, running Android Studio 3.5 and java openjdk version "1.8.0_222"

** build.gradle File**

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.4.1")

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

        google()
        jcenter()
    }
}

**执行./gradlew时出错：RNTester：android：app：installDebug **

引用fixing commit from the React Native repo：

之所以发生这种情况，是因为 buildReactNdkLib 任务已被创建并配置。因此，此PR更改了一些需要延迟配置的任务，并在准备好后从 android 读取值。还要删除ANDROID_NDK变量检查，因为android gradle插件会自动执行此操作。

问题已于昨天在react-native#master上解决。尝试获取最新更改并构建RNTester！
