Hi, this is the first time I try to push something on github and deploy here, I’m a total beginner, so I have no idea what went wrong.
This is the site name: https://grand-sunshine-d97e87.netlify.app/
It deploys from this repo in github: GitHub - NoNameOverlord/random-quote-machine: Random Quote Machine for a FreeCodeCamp project, functional but not styled
When I work locally on Visual Studio, the code works and it shows the page as it should be with all its functionalities, but I can’t seem .
I have already tried to change “npm run build” to “CI= npm run build” to no avail.

Here the full building log:

I tried to drop the project manually here on Netlify: https://resilient-queijadas-a33cb9.netlify.app/
Yet, while I can see the files are there, the website shows just a blank page and none of its functionalities.

@francesco.barzetta The error is shown in the log:

When you say:

This will be because you’re running something different locally than on Netlify.
You’re likely running only npm run dev, which executes vite.

You should try running exactly the same thing locally that you’re running on Netlify.
Try running npm run build, which executes tsc && vite build.

If you do that you’ll see the same errors:

They are being thrown by tsc.

If you remove it from the “build” script in your package.json you will find that the build occurs, but I cannot advise if it’s necessary for your project, so you should familiarize yourself with what you’re working with and fix any errors.

I was indeed running npm run dev.
That clears up everything. I’ll try to make my code cleaner, thank you very much!

EDIT: Yes, I was silly because I thought that it was a warning and not an error. Fixed it super quickly and now everything works!
