找不到android.support.design，...播放服务，...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。我已经重新安装和更新了Android Studio，我已经清理了项目，我已经同步和失效了缓存，并重新启动了它。在构建项目(在其他PC上运行)时，我仍然收到此错误：

我的Gradle应用程序文件：

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'
}

这太让人沮丧了，请告诉我该怎么做。

Answer 1

尝试运行此命令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

Answer 2

由于您已经尝试了所有其他选项，因此我建议删除项目目录并从您的存储库执行另一次提取。或者你的文件在程序文件(x86)中，但那是愚蠢的。
