AFAIK, SSHKit::StandardError is only defined by sshkit once, at lib/sshkit.rb:3:

sshkit/lib/sshkit.rb

Line 3 in c3815c2

StandardError = Class.new(::StandardError)

The only thing I can think of that would cause this error is if there is a monkey patch in another gem that is defining the SSHKit::StandardError constant before require "sshkit" is being called. Is that possible in your setup?

As a workaround/experiment, you could try adding gem "sshkit" to your Gemfile before any other gem to see if that changes the behavior at all.

The other thing you could try is to edit your locally installed sshkit gem (e.g. using bundle open sshkit) and add this line just before sshkit defines the SSHKit::StandardError constant in lib/sshkit.rb:

module SSHKit

  pp SSHKit.const_source_location(:StandardError) # ADD THIS LINE
  StandardError = Class.new(::StandardError)

That may provide a clue as to where the duplicate constant is being defined.
