Netlify build failed for npm error in react app-CodePudding

this is the failed build log from netlify build log. I build this yesterday. Now I am having problem with building the site

I am guessing this is probably for NPM. Should I delete my installed dependency and again reinstall them using --force flag? I am using npm version 8. How can I solve this problem?

CodePudding user response：

I was facing same issue while deploying to Netlify and all the checks on my PRs were failing. After a little searching around, found the solution mentioned in Netlify forums here - Fix for Build was terminated: Build script returned non-zero exit code: 1

In my case, I was able to get the issue resolved by adding the --force flag after the build command npm run build --force. Also, had to set the NODE_VERSION env variable to 16.15.0 in Netlify as apparently the issue has occurred in Node version 16.15.1 and that was the version which was being used for build.

That's the same Node version mentioned in your post -

10:16:51 AM: Now using node v16.15.1 (npm v8.11.0)

There are few other solutions mentioned as well on the link provided above if the one's I used don't work for you.
