This error message occurs when you are trying to use a version of Node Sass that is not compatible with the version specified in your project’s package.json file. The ^4.0.0 symbol in the package.json file means that any version of Node Sass greater than or equal to 4.0.0 should work, but version 6.0.1 is not compatible.
To resolve this issue, you can either update the version of Node Sass in your project to a compatible one by running:
npm install node-sass@^4.0.0
Or, if you want to use the latest version of Node Sass, you can update the ^4.0.0 symbol in your package.json file to ^6.0.1 (or whatever version you want to use) and run:
npm install
to install the updated dependencies.
Once you have installed a compatible version of Node Sass, try running your project again and see if the error message has been resolved.
