! Two different lockfiles found: package-lock.json and yarn.lock
Both npm and yarn have created lockfiles for this application,
but only one can be used to install dependencies. Installing
dependencies using the wrong package manager can result in missing
packages or subtle bugs in production.
- To use npm to install your application's dependencies please delete
the yarn.lock file.
$ git rm yarn.lock
- To use yarn to install your application's dependences please delete
the package-lock.json file.
$ git rm package-lock.json
