我试图在本地主机上运行我的服务器进行测试，但它一直退出并出现此错误

最佳答案

这似乎是 Cloud SDK 中的一个错误，在与 App Engine 管理的虚拟机 一起使用时会影响 dev_appserver.py。它似乎不会影响 App Engine Standard 或 App Engine Flex 环境。

在 Google 发布带有修复程序的新 Cloud SDK 之前，您可以在本地修改 CLOUD_SDK_INSTALL_DIR//platform/google_appengine/google/appengine/tools/devappserver2/go_managedvm.py 文件，如下所示(已添加)可修补的统一差异以及之前/之后只是为了方便)。

同时考虑从 Managed VMs are deprecated and will not be supported after October 27, 2017 开始迁移到 App Engine Flex .

Warning: The Managed VMs beta environment (applications deployed with vm:true) is deprecated and will be decommissioned. This page is for users who are already using the flexible environment with vm:true in their app.yaml and want to upgrade to the latest release. If you are updating your application from the standard environment, see the Migrating Services from the Standard Environment to the Flexible Environment instead.

可修补格式的差异
