Cannot running on App Engine application by Python37 beta.

Hi,

>Google App Engine can run python 37

Does it work for you with Python 3.7 in the terminal?

>case python3.7

This is a known issue, please follow https://youtrack.jetbrains.com/issue/PY-31555

>case python2.7

It looks strange, there's a reference to python3 in the call for some reason. Could you please provide a full Run window output? Run Configuration and Settings | Project ... | Project Interpreter window screenshots are also welcomed.

Hi,

> Does it work for you with Python 3.7 in the terminal?
Yes.

However, dev_appserver.py needs to be run in python2.
And, target project needs to be run in python3.

$ python --version
Python 3.7.0
$ $HOME/.pyenv/versions/2.7.12/bin/python /usr/local/lib/google-cloud-sdk/bin/dev_appserver.py .

The local path is python3.
But, dev_appserver.py called by python2.
It can run.

> It looks strange, there's a reference to python3 in the call for some reason.

In the case python2.7, there doesn't has python3 path.
I think can't run pycharm by this setting. (dev_appserver.py is 2.7, and the project is 3.7)

Maybe I am missing something, but you basically run it under Python 2, I don't think python3 as the first executable in PATH plays any role here.

>case 2.7

Could you please check if you have PYTHONPATH variable defined globally in your system?

echo $PYTHONPATH should do the trick. Does it work correctly if you set the project interpreter as Python 2 instead of changing it for a run configuration?

 > I don't think python3 as the first executable in PATH plays any role here.
Want to run python37 runtime. Not python27 runtime.
https://cloud.google.com/appengine/docs/standard/python3/runtime

I'm sorry when I different, I think needs to python37 because runtime is python37.

PYTHONPATH is not set.

Can run gae, If it is python27 runtime....
But this case is python37 runtime by gae.

Is there a way to run python 37 runtime with Pycharm?

>Is there a way to run python 37 runtime with Pycharm?

It's not yet supported, unfortunately.

">case python3.7

AND 

">Is there a way to run python 37 runtime with Pycharm?

Is there any update on WHEN this will be fixed. It is not really a satisfactory answer just to say this is not supported and to link to another issue which has no updates or progress shown.

Thanks

Paul

Same issue for me,  could someone reply to give a proper reply such as whether there is a plan to support it and when?

Thank you!

Hi Yikang,

I do not have any ETA, unfortunately. But as soon as it gets In Progress status it can be expected to be released in one of the future updates.
