无法启动开发服务器

Cannot start dev server

用这个命令

dev_appserver.py .

我正在尝试部署到本地服务器,但出现错误:

我已尝试重新安装 Google App Engine SDK,但仍然没有成功。知道为什么它不起作用吗?之前它一直有效,直到我听了它并更新了 Cloud SDK。

您正在使用与 gcloud 捆绑在一起的 dev_appserver,它有时不是完全最新的。要绕过该问题,请按照 https://cloud.google.com/appengine/downloads?hl=en to download and install GoogleAppEngine-1.9.30.msi -- and make sure you use that dev_appserver. Also, please open a bug report about the gcloud-bundled dev_appserver at https://cloud.google.com/appengine/downloads?hl=en 处的说明进行操作(使用您在此处发布的相同信息加上您的确切 OS 和 gcloud components list 的结果来准确指出哪些组件存在错误),谢谢。

(理论上,您观察到的错误可以用 app.yaml 中错误的 skip_files 节来解释,但如果是这种情况,那么它以前不应该使用不同的 dev_appserver 发布)。
