Hmm.. not working for me either.. used to work...

Hmm.. deciphering error messages has lead me to this, which is working a bit...

pulumi --verbose=true plugin install resource x v1

I think there's a bug though. Some messages say that it wants no "=" and an int, but when I do that, it complains about having too many arguments. Looks like arg parsing is a bit shot, at the moment...

it's something we need to fix

as it would be very useful to get a lot more info

To circle back here, I jsut opened a PR to allow the following information:
