My yarn version v1.22.5 I have both node version 12 and 15 it uses 15 as default

Answer 1

I found the solution. The problem was with my /Users/name/package.json. To solve it you need to erase your node modules and package.json. Then you need to do npm install, npm install yarn. For my case i did this in /Users/[name]/ folder.
