React Native version Mismatch - 原生版本：0.59.5

Question

我在Android模拟器上收到此错误：

React Native版本不匹配：Javascript版本：0.58.5原生版本：0.59.5

我已经升级了React Native，模块，Android工作室以及我能做的一切。在iOS上一切正常，这只发生在Android上。构建是成功的

的package.json

  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",

  "jest": {

  }
}

的build.gradle

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
        googlePlayServicesVersion = "15.0.1"
        androidMapsUtilsVersion = "0.5+"
    }
    repositories {
        google()
        //mavenLocal()        
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.2.0'

    }
}

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

/*
task wrapper(type: Wrapper) {
    gradleVersion = '4.7'
    distributionUrl = distributionUrl.replace("bin", "all")
}*/





   dependencies {
        implementation project(':react-native-firebase')
        implementation project(':react-native-gesture-handler')
        implementation fileTree(dir: "libs", include: ["*.jar"])
        implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
        implementation "com.facebook.react:react-native:+"  // From node_modules
        implementation project(':react-native-linear-gradient')
        implementation project(':react-native-maps') 
        implementation "com.google.android.gms:play-services-base:16.0.1"
        implementation project(':@react-native-community_async-storage')

        implementation ("com.google.firebase:firebase-core:16.0.7") {
            exclude group: 'com.google.android.gms'
        } 

        implementation ("com.google.firebase:firebase-auth:16.1.0") {
            exclude group: 'com.google.android.gms'
        } 

        implementation ("com.google.firebase:firebase-database:16.0.6") {
            exclude group: 'com.google.android.gms'
        }
    }

我试过关闭所有终端，纱线安装，创建新的Android设备。我猜它与Package.json中的React Native的实际版本有关，但它是0.59.5，当我搜索整个项目时，我无法在任何地方找到任何对0.58.5的引用。

谢谢卢克

Answer 1

我在github论坛的帮助下解决了这个问题。这个错误是在我的情况下通过在模拟器中安装Android 9引起的。安装Android版本8的新设备解决了这个问题。

Answer 2

确保package.json中的RN版本与android/app/build.gradle中的版本相同，它应该如下所示：

在package.json中

"react-native": "0.59.5",

在android/app/build.gradle

implementation ("com.facebook.react:react-native:0.59.5") { force = true 
}

编辑：您还可以检查打包器和模拟器/设备是否在同一网络中，并从正确的位置获取JS包？看起来你的应用程序在构建时没有得到更新，它被困在旧代码中。

希望这可以帮助。快乐的编码！
