Yarn has introduced a new approach to install dependencies: plug’n’play, it will be the default option for Yarn 2.
PNP means that Yarn will not copy dependencies to node_modules, it will create .pnp.js file and inject hooks into NodeJS resolution mechanisms.
Currently I Sonar Scanner seems to be unaware of that and fails with error:
ERROR: Cannot find module 'typescript'
