Google App Engine Launcher crashes on OSX

[Matt Seaborn]

My Google App Engine Launcher crashes on my mac with EXC_BAD_ACCESS (SIGSEGV).

When I run a Python project on the launcher, it starts running but the launcher crashes when the project receives HTTP communication such as POST or GET.

 - Google App Engine Launcher 1.9.30 (latest) 

 - mac os x 10.11.2  (latest) 

 - Python 2.7.10

 

The same issue as this one http://stackoverflow.com/questions/34446267/google-app-engine-launcher-crashes-on-mac/ however deleting the datastore (which resolved that post) doesn't help.

It still may be worth posting this as a new question to Stack Overflow and referencing the old one, since in your case the solution didn't work.

Are you seeing any issues when you run the application without the launcher, using 'dev_appserver.py app.yaml' from your app's directory?

...

It's not directly related but it's a great idea to just use the command line tools

On OSX, any google program acts like a malware anyway, popping up continuously for updates with no clear path to disable interruptions

I just download the SDK source, run it with python, it just works

(the GUI launcher does some extra stuff tho, like persisting search db etc., if you decide to run things from the command line, you will have to solve some things manually)

Already done, Adam: http://stackoverflow.com/questions/34532833/google-app-engine-launcher-crashes-on-osx 

I tried the command line and it appeared to work fine.  Thanks for the tip.

Thanks, Kaan.  Command line works fine.
