Hiya, @babyrusa 
Welcome to the Netlify Forums! Thanks so much for reaching out. This Support Guide contains a ton of useful debugging tips that can likely help you solve your problem 
Additionally, this Support Guide houses all of our resources for debugging build and deploy issues.
We also recommend trying to search the forums with the build error you encountered - it’s likely your question was already asked by someone else!
If you are still having problems, please provide what you have already tried, a link to your live site, your most recent deploy log, what your build settings are, your package.json, etc. Thanks!
