Netlify site name: noona.is

I’m facing a build error: Error running command: Build script returned non-zero exit code: 2
Local build works and it works as well via the Netlify Docker image: https://github.com/netlify/build-image#running-locally

I found a similar issue but there doesn’t seem to be a sufficient solution here: Failed during stage 'building site': Build script returned non-zero exit code: 2

Is there a way to get more detailed error of what’s happening?

I tried limiting the memory in docker run by modifying the start-image.sh script as seen below. It still succeeds building locally.

hi there, this might be a useful read:

Thanks. It works to set the CI environment variable to false/undefined.

In your opinion, would this be classified as a bug from create-react-app? Should it be able to handle the CI environment variable to be truthy?

The answer is “it depends” - some people expect that to work differently than others. Too bad it is a “de-facto” standard rather than one that is documented and universally agreed upon.

From their point of view, they are doing what they intend. From others’ points of view, such as ours, they are doing it differently than the people who created the convention perhaps intended…

I suspect if you file a bug on their project, they’ll tell you the same thing, but I’m not sure :slight_smile:

#6

Interesting. Is this a requirement for all React apps that are created with create-react-app? To specify CI= prior to their build?

Nope! Only ones that don’t run without warnings, which you want to run in a CI system like Travis or Netlify :slight_smile:

Ah, got it. Thanks :grinning:

I found this post to be a good read if anyone’s interested in diving deeper: How to fix build failures with `create-react-app` in production
