Android React Native:无法解析配置的所有文件'；：app:debugCompileClasspath'；

我是一个新手，会以本地的方式做出反应，遵循指南，现在我正试图编译我的第一个android应用程序。不幸的是，控制台输出：

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all files for configuration ':app:debugCompileClasspath'.
> Could not find support-vector-drawable.aar (com.android.support:support-vector-drawable:27.1.1).

我跳过了哪些步骤？我的平台是Windows 10，我的Android手机是7.1.1。

我只是添加了：

maven{url'https://maven.google.com“}

致：android/build.gradle

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

我想这是一个渐变版本的问题

我刚刚解决了添加：

<代码>maven{url'https://maven.google.com“}

致：android/build.gradle

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

我猜这是一个渐变版本的问题

它符合这个问题！这符合问题！
