Make sure you have an Android emulator running or a device connected and have set up your Android development environment: https://facebook.github.io/react-native/docs/android-setup.html

Answer 1

这通常是您的 gradle 文件中的存储库有问题。

对我来说，像这样修改 build.gradle:

buildscript {
    repositories {
        mavenLocal()
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

所以当你添加 google() 时它应该可以工作。
