无法运行简单的helloworld令人沮丧。

我遇到的错误： -

解决方案

github上的文件和是你的helloworld文件似乎并没有被命名为helloworld.py。可能会有帮助吗？

另外，您是否需要在helloworld顶部的PROJECT_DIR变量？

如果你正在努力使基础教程工作，你应该做的第一件事是确保你的项目与谷歌的例子完全一样。

I am trying to run the official helloworld program in google-appengine 1.6.4 for python 2.7.

It's so frustrating to be not able to run a simple helloworld. I would appreciate any kind of help here.

Error I encounter:-

解决方案

One difference between the files that you have on github and the official google hellworld tutorial is that your helloworld file doesn't seem to be named helloworld.py. Potentially that would help?

Additionally, do you need that PROJECT_DIR variable at the top of helloworld?

If you are struggling to get the basic tutorial working, the first thing you should do is make sure that your project is literally the exact same as the google example.
