How do I run the chef knife plugin?

Question

I would like to use a knife plugin. e.g. KnifeSpork I got the plugin installed. But I get errors when I try to run it.

First try

Install KnifeSpork:

$ gem install knife-spork

Run KnifeSpork:

$ knife spork info

Output:

FATAL: Cannot find subcommand for: 'spork info'
Available subcommands: (for details, knife SUB-COMMAND --help)

** CHEF ORGANIZATION MANAGEMENT COMMANDS **
knife org create ORG_SHORT_NAME ORG_FULL_NAME (options)
knife org delete ORG_NAME
knife org edit ORG
knife org list
knife org show ORGNAME
knife org user add ORG_NAME USER_NAME
knife org user remove ORG_NAME USER_NAME
....

Second try

Create a Gemfile

source 'https://rubygems.org'

gem 'knife-spork'

Install the dependencies

$ bundle install

Run KnifeSpork:

$ bundle exec knife spork info

Output:

Could not find ffi-1.15.4, ffi-yajl-2.4.0, libyajl2-2.1.0, json-2.6.1 in any of the sources
Run `bundle install` to install missing gems.

Here is how I was able to get spork installed on the latest version of chef-workstation (23.4) on a M2 mac.

Install Chef-workstation

brew install --cask chef-workstation

Add ruby to your path

echo 'export PATH="~/.chef/gem/ruby/3.1.0/bin:$PATH"' >> ~/.zshrc

Open new terminal window

Install spork

chef gem install knife-spork
