Failed at the node-sass@4.12.0 postinstall script.

[Dev@2609]

Hi Team, I downloaded the demo version of the product and while trying the examples of the angular advanced I am getting error for node-sass module.

I have tried removing the package.json.lock file, deleted node modules and reinstalled the npm as well still no effect. Also tried to install npm install node-sass as well.

Any help would be appreciated.

I have tried it but it works without problems. See the video.

Can it be that you have node-sass installed globally? Also, there is no reference to node-sass in advanced/package.json.

Also, node version 12 is not supported. Please install node 10 from here: https://nodejs.org/dist/latest-v10.x/

Reinstalling angular cli and degrading typescript version to 3.4.5 did it for me... Thanks for your help
