knife-vsphere plugin not working

Question

Following adding 'knife-vsphere' to my cookbook's Gemfile:

gem 'knife-vsphere'

I try to use the following command:

knife vsphere vm list

And i get the following error: "FATAL: Cannot find sub command for: 'vsphere'"

Clearly knife isn't even aware that it's installed, but it is.

Answer 1

Use

chef gem install knife-vsphere

to install it into ChefDK's ruby (docs).
