How do I downgrade a package in devDependencies with yarn?

Question

I want to downgrade a package version from 3.0.1 to 3.0.0? I've tried yarn upgrade @...Also tried with --dev, but it didn't work. I wasn't able to find the answer.

Answer 1

You can add the desired verion number to the back of the package name like so:

yarn add packagename@3.0.0

Edit:

If wanting to add to devDependencies instead:

yarn add -D packagename@3.0.0
