Running production and creating distribution files fails

[vboctor]

Just cloned the repository and got the app running in debug mode, but production mode and creation of distribution files are failing.

 electron-react git:(master) ✗ npm run dist

> npm run prod && electron-builder


> [email protected] prod /Users/vboctor/js/electron-react

        ^

Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.

I just cloned it and it's building the prod correctly. From a quick google search, looks like you just need to remove your build files and run the command again.

@tahnik i'm getting the same error @vboctor got. What version of node are you using ?

[tahnik]

@hemantasapkota version 9.5.0

Did you try removing package-lock.json?

EDIT: I just fixed an error related to extract-css-webpack-plugin. Pull the latest and see if it fixes your issue.
