hey there,
it seems like you are asking us to run a build command that isn’t defined in your package.json:
7:38:33 PM: npm ERR! Exit status 1
7:38:33 PM: npm ERR!
7:38:33 PM: npm ERR! Failed at the gatsby-starter-default@0.1.0 build script.
7:38:33 PM: npm ERR!
I would make sure that the project builds locally before pushing it.
This Common Issue contains a ton of useful debugging tips that can likely help you solve your problem 
If you are still having problems, please provide as much information as you can on what you have already tried, what your build settings are, your package.json, etc. Thanks!
