I think much like NODE or NPM we get ourselves into these modes sometimes where what should be a simple question leads to a Google Search and of course, a StackOverflow Discussion 🙂
How do you upgrade the package that installs and updates packages?
The answer isn't obvious at all:
yarn policies set-version
From the Documentation, there is this note:
Note that this command also is the preferred way to upgrade Yarn - it will work no matter how you originally installed it, which might sometimes prove difficult to figure out otherwise.
