java - gcloud Preview 应用程序在 Windows 上运行 "bad port Access Denied"错误

Question

我正在尝试设置一个多模块 Appengine 应用，其中一个模块作为托管虚拟机。

但对于初学者来说，我正在检查是否可以在此处运行在 AppEngine Java 多模块示例上运行的 gcloud 预览应用程序: https://github.com/GoogleCloudPlatform/appengine-modules-sample-java

当我将其导入 Android Studio 并运行 appengineRun 构建规则时，它构建得很好。但是，如果我进入命令提示符并运行以下命令:

E:\appengine-modules-sample-java-master>gcloud preview app run appengine-modules
-guestbook/src/main/webapp

然后我收到以下错误:

对于我尝试通过 gcloud Preview app run 运行的任何 Java AppEngine 模块，我都会遇到相同的错误。 gcloud 应用程序不支持运行 Java AppEngine 模块吗？

我做错了什么？

更新:截至今天，我使用最新的 gcloud 工具再次运行该命令，但仍然收到上述错误。

只有当我在 Windows 上运行时才会出现此问题。以管理员身份运行命令提示符并执行 gcloud 命令可修复此“端口错误/访问被拒绝”问题。
