我尝试为 android 编译快速测试示例数据库游戏，但我得到“一个或多个 Firebase 依赖项不存在。当前依赖项状态：UnavailableOther”。 所以我尝试使用 Asserts > Play services Resolver > Android Resolver > Resolve Client Jars。它将打印回此错误列表。请帮帮我。

【问题讨论】：

打开您的 Android SDK 管理器并下载 Google Play 服务。它是 Firebase 依赖项之一。

我已经下载了 Google Play 服务和 Google Play 存储库。还是一样的。

【参考方案1】：

Firebase 插件与许多其他插件一样，使用 Play services resolver 来解决所需的依赖关系。

从错误消息来看，解析器似乎无法找到它正在寻找的内容：

Unable to find dependency com.google.android.gms:play-services-base:10.2.4 in paths ($SDK\extras\android\m2repository, $SDK\extras\google\m2repository).

请注意，路径以 $SDK 开头，而不是真正的真实文件夹。

您应该确保您的 Android SDK 路径在 Unity 中的 Preferences -> External Tools 下正确设置。

另外，请确保您拥有最新版本的 Google Play 服务（通过 SDK 管理器，确保“Extras”下的内容是最新的）。
