My .sublime-build is:

{ "working_dir": "$project_path", "cmd": "sh", "-c", "dev_appserver.py", "--port=9090"], "encoding": "UTF-8", "shell": true }

But then all I get is “[Finished in 0.1s]” - but dev_appserver.py never does finish - it runs continually from invocation until quit (at which point it stops serving). And sure enough if I check port 9090, it isn’t running.

Executing these same commands in Terminal works just fine though:

$ cd /project/path $ dev_appserver.py --port=9090

What have I missed, or done wrong?

Thanks in advance,
