warning package-lock.json found

[gandarez]

When running yarn install pops up an warning

warning package-lock.json found. 
Your project contains lock files generated by tools other than Yarn. 
It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. 
To clear this warning, remove package-lock.json.
