I was deploying my react page on netlify when I got this error "Build failed due to a user error: Build script returned non-zero exit code: 2"

I saw some warnings related to variable dependencies not being in the useEffect but I didn't want to solve it, so I tried finding a new solution.

and then I saw this:

12:39:50 AM: Treating warnings as errors because process.env.CI = true.
12:39:50 AM: Most CI servers set it automatically.

I thought maybe setting this CI variable to false would solve my problem, and it did so here's the solution for you, if you are suffering from the same.

• the first step is to find deploy settings in your netlify app.

  

• just find deploy settings and scroll down to the environment variables section which looks like this:

  

• add the new variable CI with the value 'false'.

• deploy your site again and the error will be solved.
