$ yarn --ignore-engines

npm doesn’t install the version of dependency from package-lock.json

this can happen if you tried to install that depedency explicitly beforehand (say, by adding it to dependencies or devDependencies in package.json) but uninstalled it in the end. still incorrect version of that depedency (the one you specified in package.json) is resolved over and over again.

solution

clean npm cache:

$ npm cache clean --force
$ npm install
