我试图运行我的服务器在localhost上进行测试，并且它一直在退出此错误
答案 0 :(得分：1)
这似乎是Cloud SDK中的一个错误，与dev_appserver.py一起使用时会影响App Engine Managed VMs。它似乎不会影响App Engine Standard或App Engine Flex环境。
在Google发布带有该修补程序的新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（为方便起见，同时添加了可修补的统一差异以及之前/之后）。
同时考虑从Managed VMs are deprecated and will not be supported after October 27, 2017开始转移到App Engine Flex。
警告：托管虚拟机测试版环境（部署了应用程序的应用程序）
vm:true）已弃用，将退役。此页面适用于 已经使用vm:true的灵活环境的用户 他们的app.yaml并希望升级到最新版本。如果你是 从标准环境更新您的应用程序，请参阅 Migrating Services from the Standard Environment to the Flexible Environment instead
