I've done this recently and used the following approach:
In my Gemfile I had (as a global gem):
gem 'wicked_pdf'
then in an initializer I have:
WICKED_PDF = { :wkhtmltopdf => (Rails.env.test? || Rails.env.development? ?
'/usr/local/bin/wkhtmltopdf' : Rails.root.join('bin',
'wkhtmltopdf-amd64').to_s), :exe_path => (Rails.env.test? ||
Rails.env.development? ? '/usr/local/bin/ ' : Rails.root.join('bin',
'wkhtmltopdf-amd64').to_s) }
So, wkhtmltopdf-amd64' is committed into a local bin folder and used by
wicked_pdf as the binary in anything other than development, where it uses the
local path of the installed binary.
Hopefully this makes sense.
