Sage 9 doesn’t yet completely support tw2 but there are PRs awaiting…

You will need to git clone the repo branch:

`git clone --branch 9-webpack5-tailwind2 git@github.com:ciromattia/sage.git theme_name `  
changing “theme\_name” to your desired name

and update your devUrl and proxyUrl in config.json here:  
`theme/resources/assets/config.json`

and proxyURL here:  
`assets/build/config.js`

Then run from the root of the theme folder:  
`yarn && yarn build`

Then run from the root of the theme folder:  
`composer install`

That should get you up and running. This fork includes postcss-nesting so scss is not supported.
