Fails with Yarn

[Kristian Dupont]

I am seeing this:

$ npx how-outdated
npx: installed 1 in 1.237s
NaN error undefined undefined

I am using Yarn which might be the reason?

Thanks for the bug report :)
Yes I have only implemented support for npm.
If something like yarn outdated --json works, I will see if I can get support for Yarn added.
PRs are also welcome!

It appears that it's because I am using Yarn workspaces, and thus have a non-external dependency which confuses npm. I will close this.
