Create-react-app cannot build. it takes long time and then got error

Question

I have create-react-project v15 and run npm run build and takes long time (20mins)(like freezing) for running build then got this error result.

How to Fix this?

enter code heresers/rice/my-app-2/node_modules/extract-text-webpack-plugin/dist/index.js:246
        if (extractedChunk.getNumberOfModules()) {
                           ^

The clue is in the error "extractedChunk.getNumberOfModules is nota function". You're probably not exporting that function properly, but without seeing your code it's impossible to tell. — Andy, Mar 19 '18 at 09:24
this package-module is come from create react app module => extract-text-webpack-plugin. I dont know to fix — riseres, Mar 19 '18 at 09:26
My guess is that you should change extractedChunk.getNumberOfModules() to extractedChunk.getNumberOfModules , without the () — Mihai T, Mar 19 '18 at 09:27
@MihaiT I have changed as you guided the result is the same. freezing build — riseres, Mar 19 '18 at 09:32

Maybe you can try to delete the node_modules folder and run npm install again to reinstall the modules.
Then try running npm run build again.
