Missing yarn dependencies

[flovntp]

Hi,

when trying to install a new Symfony demo app on Platform.sh, using:

symfony new symfony-demo --demo --cloud
cd symfony-demo
symfony cloud:create
symfony deploy

i get this error during PSH deploy

yarn run v1.22.19
          $ /app/node_modules/.bin/encore production
          W: node:internal/modules/cjs/loader:998
          W:   throw err;
          W:   ^
          W: Error: Cannot find module '@babel/core'

When running yarn install, some dependencies are missing so i needed to add them into package.json for deployment to success

yarn install v1.22.18

And upgrading sass-loader to version 13 as well to avoid having this warning during PSH deploy:

           WARNING  Webpack Encore requires version ^13.0.0 of sass-loader, but your version (12.6.0) is too old. The related feature will probably *not* work correctly.

hope it helps.
