How to let npm run build shows errors?

[zeroarst]

Today I came across an issue that my npm build command does not generate any build files. I narrow down the issue and I found it could be some errors in my code. But I thought webpack should at least log something, instead of nothing.

I test this issue with a clean clone of this repo, and add below to any js files.

import '/something/does/not/exist'

This path has nothing. Then when I do npm build, there is no build files and no errors on the console.

How do I configure webpack to show errors?
