I tried this but it didn't work for me and threw errors:
npm --depth 9999 update
npm rebuild node-sass
I have installed the latest Node.js
(which for the moment is 11.11.0 Current), after facing this problem I just did the following:
- downgrade to recommended version (which for the moment is 10.15.3 LTS)
- you can get it from NodeJS,
- deleted node_modules and
- then reinstall yarn:
yarn install
yarn start
After executing these commands everything is working fine for me.
