Interesting that the repro from #2819 still logs a warning in 0.23.2. What is its purpose?

yarn init -y && yarn add sequelize-cli && yarn add gulp --dev && yarn --prod && yarn check --verify-tree --prod

I find the 2 last commands interesting

yarn install v0.23.2
[1/4] 🔍  Resolving packages...
warning Integrity check: Flags don't match
[2/4] 🚚  Fetching packages...
[3/4] 🔗  Linking dependencies...
[4/4] 📃  Building fresh packages...
✨  Done in 2.09s.
yarn check v0.23.2
success Folder in sync.
✨  Done in 1.01s.

Why complain about "Flags don't match" when it's not wrong? What actions can I as a user do? And what does it really mean?

Good point, @SimenB.

So let me explain:

yarn init -y && yarn add sequelize-cli

adds sequelize-cli to dependencies in non production mode

yarn add gulp --dev

adds gulp to dev dependencies in non production mode

yarn --prod

installs dependencies in production mode.
Because previous install (add gulp) was done in non production mode the integrity check does not pass and Yarn proceeds with doing a full installation.

But I think you are right, there should not be a warning, I added it for information purposes when running yarn check --integrity.
I think integrity checker should not report, check.js command should do that.
