npm Webpack code ELIFECYCLE errno 1

When building the PiCockpit frontend code (which is packaged using Webpack) on a different computer, I ran into the following issue:

The typical suggestion online to fix this error is to remove node_modules, to remove package-lock.json and to reinstall the modules using npm install.

This did not work for me, the error persisted.

Here is what worked:

I looked at webpack.config.js and disabled parts of it, until I had my culprit. The two following lines had to be commented out, to make the configuration work:

// devtool: ‘#eval-source-map’,

// module.exports.devtool = ‘#source-map’

It might be different in your case – I recommend to try and experiment with webpack.config.js as necessary.
