找不到 com.android.tools.build:gradle:2.3.+ 的任何匹配项

当我尝试通过react-native run-android 构建我的应用程序时，出现此错误。昨天还好好的，今天突然就报错了。

我已经检查过 React Native 矢量图标，它看起来不错，这也适用于 iOS。

这是错误：

   * What went wrong:
A problem occurred configuring project ':react-native-vector-icons'.
> Could not resolve all files for configuration ':react-native-vector-icons:classpath'.
   > Could not find any matches for com.android.tools.build:gradle:2.3.+ as no versions of com.android.tools.build:gradle are available.
     Searched in the following locations:

         https://jcenter.bintray.com/com/android/tools/build/gradle/
     Required by:
         project :react-native-vector-icons

这是我的 gradle 文件：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:3.2.0'
        classpath 'io.fabric.tools:gradle:1.+'

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

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

ext {
    buildToolsVersion = "26.0.1"
    minSdkVersion = 16
    compileSdkVersion = 26
    targetSdkVersion = 26
    supportLibVersion = "26.1.0"
}

subprojects {

 project.configurations.all {
    resolutionStrategy.eachDependency { details ->
       if (details.requested.group == 'com.android.support'
              && !details.requested.name.contains('multidex') ) {
           details.useVersion "26.0.1"
        }
     }
  }

  afterEvaluate {project ->
      if (project.hasProperty("android")) {
          android {
              compileSdkVersion rootProject.ext.compileSdkVersion
              buildToolsVersion '26.0.1'
              defaultConfig {
                  targetSdkVersion rootProject.ext.targetSdkVersion
              }
          }
      }
  }
}

我在这里缺少什么？

尝试将“react-native-vector-icons”包更新到最新版本（6.1.0）。
