找不到com.android.support:AppCompat-v7:25.3.1

Question

我在尝试构建时突然开始出现这个错误。这一切都是在几个星期前的工作，没有任何变化，我知道。这个问题似乎与react-native-fbsdk有关，但查看它的build.gradle，它没有列出support.appcompat-v7.25.x。有什么建议吗？

我在一个android项目上遇到过同样的问题(AppCompat-V7:25.3.1)，但没有使用React。

我首先尝试清理gradle缓存(~/.gradle/caches)，就像这里解释的那样，但没有帮助。

然后我查看了SDK管理器。
Android支持库通常通过SDKManager安装。然后将库存储在本地maven存储库中: /sdk/extras/android/m2repository/ 。

我还找到了另一种获取支持库的方法：远程获取。阅读此处(https://developer.android.com/topic/libraries/support-library/setup.html#add-library)并如下所示修改 /build.gradle :

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}
