I got the error “build. command” failed. I added the command CI= npm run build and still, the error continues.

My application is in React.js, I don’t know what else to do, and I am waiting for your help.
Thanks in advance.

There needs to be a space here. It should be CI= npm run build.

Hi hrishikesh,
Thank you for helping me. I added a space following your advice, however, after “clear cache and deploy site”, it still shows the error. What should I do?

Hello, may I know what structure or file name format you used to solve the problem?

It was saved as a Capital letter, but when I placed img was in lowercase, so I received an error.
