I’m trying to deploy my ghost blog on netlify. I found a GitHub starter kit that I’m trying to deploy but I always get the same error. here’s the netlify link: soundsiriusblog.
10:11:04 PM: $ NODE_ENV=production gatsby build
10:11:07 PM: error We encountered an error while trying to load your site’s gatsby-config. Please fix the error and try again.
10:11:07 PM: Error: siteUrl can’t be localhost and needs to be configured in siteConfig. Ch eck the README.
Looks like your trying to use the default siteConfig.js
Update your siteUrl and you should be fine 
but if I just want to deploy my blog on Netlify, how can I do it? When running a local ghost, the website is accessible on localhost:2368. I’d like to deploy the website part (without the ghost software obviously) and upload it on Netlify. How do you do that? This is a temp solution while I’m battling with Gatsby and GitHub.
As the README states, “Finally, configure your desired URL in siteConfig.js , so links (e. g. canonical links) are generated correctly. You can also update other default values, such as postsPerPage in this file.”
If you have a custom domain, set it to be that instead of localhost. Otherwise, you can use the .netlify.app name provided!
