Question

我有一个Ubuntu主机，使用APT在其上安装了OpenJDK 10和Gloud SDK。当我尝试安装“ google-cloud-sdk-datastore-emulator”时，出现以下错误。我在GCP GitHub上找到了一个讨论此问题的线程，但该线程已关闭。此处-https://github.com/GoogleCloudPlatform/cloud-sdk-docker/issues/144

还有其他人遇到这个问题吗？

错误-

//let urlHost : String = url.host as String!
//let mainStoryboard: UIStoryboard = UIStoryboard(name: "BLE", bundle: nil)
//if(urlHost == "BLELoginViewController")
//{
//    let innerPage: BLELoginViewController = mainStoryboard.instantiateViewController(withIdentifier: "BLELoginViewController") as! BLELoginViewController
//self.window?.rootViewController = innerPage
//}

Answer 1

我们的debian软件包依赖性配置存在一些问题。尽管如果您通过gcloud命令安装模拟器，它应该可以工作：

gcloud component install cloud-datastore-emulator

（https://cloud.google.com/sdk/gcloud/reference/components/install）

请注意，如果从其他程序包管理器中安装了sdk，则组件管理器将无法工作。在这种情况下，您可以删除它并按照以下建议进行安装：stackoverflow.com/questions/42697026

如果由于某些其他原因您必须通过apt-get安装，https://serverfault.com/questions/250224应该会有所帮助，基本上避免通过以下方式安装openjdk：

apt-get install google-cloud-sdk-datastore-emuilator openjdk-8-jdk-

请注意，openjdk-8-jdk后面有一个“-”

或者您可以按照同一线程中的步骤更新程序包依赖性。

我的解决方案涉及使用equivs创建一个伪造的openjdk-8-jdk软件包（当然，您需要确保您拥有另一个JDK）。

apt-get install equivs
equivs-control openjdk-8-jdk
vim openjdk-8-jdk # especially change the package name, but I also used 11.0.0 as a version (although it's probably not needed)
equivs-build openjdk-8-jdk
dpkg -i openjdk-8-jdk*.deb

GCP数据存储模拟器不会安装在OpenJDK 10上
