如何修复上的OpenAPI文档生成？

Question

我正在学习本教程：“在App标准上开始使用Cloud框架”。https://cloud.google.com/endpoints/docs/frameworks/python/get-started-frameworks-python

在步骤2中的“生成OpenAPI文档”部分中，在用我的项目ID替换'MY_PROJECT_ID‘之后运行命令时：

python lib/endpoints/endpointscfg.py get_openapi_spec main.EchoApi --hostname [MY_PROJECT_ID].appspot.com

我得到以下错误：

Traceback (most recent call last):

    main(sys.argv)

有人知道怎么解决这个问题吗？

感谢您使用云终结点框架。

这是框架版本4.7.0中引入的一个bug。我已经打开了https://github.com/cloudendpoints/endpoints-python/issues/184来跟踪它，并将尝试尽快修复它。
