How to remove the SW Precache? --> error on *npm install*

[Richacinas]

I'm trying to remove the sw-precache-webpack-plugin because I don't need this feature on my app, however, I'm getting an error on install (and the build that comes with it).

I just remove the dependency from package.json and the block of the plugin SWPrecacheWebpackPlugin configuration in webpack/prod.config.js.

Now, when running:

npm install

I'm getting:

Fixed by bumping these two PostCSS libraries in package.json to the versions that you can read below. I don't know if only one of them is needed to be updated... but here they are:

"postcss": "~7.0.16",
"postcss-cssnext": "~3.1.0"

Tough one.. I hope it helps someone else!
