android - 找不到 android.support.design，...play-services，...support，...appcompat

Question

我知道有很多类似的问题，但我确实尝试了那里描述的解决方案但没有成功。我已经重新安装并更新了 Android Studio，清理了项目，同步并使缓存失效并重新启动了它。我在构建项目(在其他 PC 上运行)时仍然出现此错误:

Error:A problem occurred configuring project ':app'.

我的 Gradle 应用文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "myapp"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.loopj.android:android-async-http:1.4.9'
    compile 'com.google.code.gson:gson:2.4'
    compile 'com.google.android.gms:play-services:9.0.1'
    compile 'com.android.support:support-v4:23.4.0'
}

这非常令人沮丧，请告诉我该怎么做。

尝试运行它以在本地安装所需的库:

android update sdk --no-ui --all --filter tool,extra-android-m2repository,extra-android-support,extra-google-google_play_services,extra-google-m2repository,android-23
