Can't deploy React Project. Error is Command failed with exit code 1

Question

I wrote my React project and can run on localhost and also I can build with yarn build command on my computer.

I pushed my project to github ( Repo ). When I want to deploy to my project to Vercel or Netlify I'm getting error which is Cannot find file '../../components/collection-item/Collection-item' in './src/pages/collection'. but there is no problem with path or something as I said I can run and build it my own computer. I couldn't find a solution. I changed file name and path still same.

Here is Netlify Logs:

Answer 1

Go in package.json and in scripts, replace build with this:

"build": "CI= react-scripts build",

Answer 2

Answer for people who has same problem.

In my case I changed some of my files name to capitalize version. The problem was Git didn't resolve this change that's why my file structure was wrong on Github. So Solution is changind this config with git.

git config core.ignorecase false this command makes git to be aware of capitalization.

Here is another question on Stacoverflow: I change the capitalization of a directory and Git doesn't seem to pick up on it
