If you haven't logged into the github package repository, you'll need to run:
npm login --repository https://npm.pkg.github.com
If you're using 2FA, you'll need to create a Personal Access Token with all the repo:
and read:packages
scopes.
This will be your password when prompted.
After that is taken care of, you can just run:
npm install
npm run serve
npm run build
npm run lint
