Hey @angelangweihan , have you been able to successfully build your site locally?
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 a link to the deploy log from the Netlify UI and provide as much information as you can on what you have already tried, and we can work from there!
