第一次运行到安卓失败

Could not find implementation class 'com.facebook.react.ReactRootProjectPlugin' for plugin 'com.facebook.react.rootproject' specified in jar:file:/D:/Android_Studio_Data/.gradle/caches/jars-9/o_3a1fd35320f05989063e7069031b710f/react-native-gradle-plugin.jar!/META-INF/gradle-plugins/com.facebook.react.rootproject.properties.

修改android下的build.gradle

buildscript {
    ext {
        buildToolsVersion = "34.0.0"
        minSdkVersion = 21
        compileSdkVersion = 34
        targetSdkVersion = 34
        ndkVersion = "25.1.8937393"
        kotlinVersion = "1.8.0"
    }
    repositories {
        maven{ url 'https://maven.aliyun.com/repository/google'}
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin")
    }
}
allprojects {
    repositories {
        maven{ url 'https://maven.aliyun.com/repository/google'}
        google()
        jcenter()
    }
}

apply plugin: "com.facebook.react.rootproject"

打开app,满屏红色，状态500

关闭这个，重新运行

如果还不行

npm uninstall babel-preset-react-native

npm install babel-preset-react-native@2.1.0 —save

或

yarn remove babel-preset-react-native

yarn add babel-preset-react-native@2.1.0
