android - React Native AIDL 缺失

Question

我是 React Native 的新手，我已经安装了 node.js、Java 8 和 Android Studio 3 及其 sdk 和工具

我坚持在我的模拟器上运行 React Native :

react-native run-android

它显示的错误是这样的:

Execution failed for task ':app:compileDebugAidl'.
java.lang.IllegalStateException: aidl is missing

我已经尝试下载 Android Marshmallow (23) 和构建工具版本 23，更改 gradle 版本，但这并没有修复我的错误。

我的build.gradle

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

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

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

我错过了什么？如何解决？谢谢

我在打开 android 项目时在 Android studio 的事件日志中收到此错误。

Instant Run requires a newer Android Gradle Plugin. Update to 3.0.1. (Don't show again)

然后，我单击“更新到 3.0.1”，错误消失了。希望这会有所帮助。
