reactNative 报错：debugCompileClass

传送门中文网地址https://reactnative.cn/

首先按照官网一步步配置好环境地址再这里https://reactnative.cn/docs/getting-started.html

将android/build.gradle中的jcenter()和google()分别替换为maven { url 'https://maven.aliyun.com/repository/jcenter' }和maven { url 'https://maven.aliyun.com/repository/google' }（注意有多处需要替换）。

遇到一些小坑：
坑1：:app:debugCompileClassPath报错

总感觉少了什么：于是照片查阅的资料在build.gradle中能加的都加上了就好了

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
    }
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.5.2")
        classpath 'com.google.gms:google-services:4.0.1'  //这行对谷歌服务库进行依赖
        // 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()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://www.jitpack.io' }
        maven {url 'https://dl.bintray.com/jetbrains/anko'}
        maven {url "https://maven.google.com"}
    }
}


task clean(type: Delete) {
    delete rootProject.buildDir
}

坑2：compileDebug not found。我是照着官网andstudio中先开了模拟器。。关掉就好了，yarn android的时候模拟器会自己开启。 image.png image.png

坑3：unable to load script,make sure you are either running a Metro server。。。
我关掉了模拟器，重新yarn react-native start 执行了一次 重新yarn android就好了。

最后就就成功了！！！
