Error: Cannot find module 'extract-text-webpack-plugin'

[juanmaguitar]

In the package.json there are these scripts..

 "scripts": {
    "clean": "rm -rf ./public/bundle.* ./src/firebase-config.json ./node_modules",
    "build": "npm run clean && npm run createfirebaseconf; NODE_ENV=production webpack -p;",
    "createfirebaseconf": "firebase setup:web --json > ./src/firebase-config.json",
    "serve": "firebase serve"
  },

When doing npm run build it will execute npm run clean which will remove the folder node_modules among other things

Because of this I'm getting this error when doing npm run build

Error: Cannot find module 'extract-text-webpack-plugin'
    at Function.Module._resolveFilename (module.js:547:15)
    at Function.Module._load (module.js:474:25)
    at Module.require (module.js:596:17)

because of course, all dependencies required in webpack.config.js (included this extract-text-webpack-plugin) are not available anymore on node_modules

I've fixed this by simply removing the ./node_modules part of the script

"clean": "rm -rf ./public/bundle.* ./src/firebase-config.json",

What was the purpose of this? Am I missing something?

@juanmaguitar Thank you!!!

This was stumping for quite some time. Yes, this appears to be an error when testing locally, if removing the npm_modules as part of the build no wonder it was not finding the modules over and over again.
