I fixed this issue by clearing the cache npm cache clean --force and runnig npm install again. But I ran into another issue while completing the installation:
npm ERR! Failed at the node-sass@3.13.1 postinstall script.

Here is my package.json:

Hello again @wjbright ,

Are you sure you are on the right Github repo?
From what i can see in your package.json there is no resemblance whatsoever with the package.json of our product.

Hello @elnazare,

Sorry, I pasted the wrong package.json

{ "name": "light-bootstrap-dashboard-react", "version": "1.2.0", "private": true, "dependencies": { "bootstrap": "3.3.7", "chartist": "0.10.1", "node-sass": "4.6.1", "node-sass-chokidar": "0.0.3", "npm-run-all": "4.1.2", "react": "16.2.0", "react-bootstrap": "0.32.1", "react-chartist": "0.13.1", "react-dom": "16.2.0", "react-google-maps": "9.4.5", "react-notification-system": "0.2.17", "react-router-dom": "4.2.2", "react-scripts": "1.1.1" }, "scripts": { "build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/", "watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive", "start-js": "react-scripts start", "start": "npm-run-all -p watch-css start-js", "build": "npm run build-css && react-scripts build", "test": "react-scripts test --env=jsdom", "eject": "react-scripts eject" } }

Hello again @wjbright ,

It is quite strange, it give you an error about node-sass@3.13.1, but in our product we use "node-sass":"4.6.1",.
Not sure what the problem could be.
Can you give me access to your project to make some tests?

Best,
Manu

Not sure if it's related, but node-sass less than 4.9 doesn't seem compatible with Node versions 10.0 or higher . I had to either downgrade Node back to 9.8 or upgrade node-sass to 4.9.x

You can see the issue here: ionic-team/ionic-app-scripts#1435
sass/node-sass#2345

I'm having the same issue. I've tried updating the versions of react, react-dom, node-sass, but nothing works.

This is the error message I get:
npm ERR! Unexpected end of JSON input while parsing near '...s":{"coveralls":"^2.1'

Node: 8.11.4
NPM: 6.2.0

Hello there @Theeeus ,

Thank you for your interest in working with our products.
If I download this product and run npm install && npm start everything works perfectly.
By updating our dependencies, there could be errors like the ones from above. Please revert the changes back to what they were.

Best,Manu
