How install a embedded gem to be used by chef-client

Chef Infra (archive)

Hi partners,

I am try to use the chef-email-reporter gem. In the documentation says:

Install the chef-email-reporter gem on the node:
/opt/chef/embedded/bin/gem install chef-email-reporter

but I am working on nodes with Windows 7 OS. Then, I use gem install chef-email-reporter and this need the Development Kit which I install following the instructions in Development Kit · oneclick/rubyinstaller Wiki · GitHub.

To use chef-email-reporter I have to put code like this in the client.rb file:

gem     "chef-email-reporter"
require "chef-email-reporter"

Mail.defaults do
  delivery_method :smtp, address: 'smtp.example.com'
end

email_sender    "no.reply@example.com"
email_recipient "chef-notifications@example.com"

and run chef-client, obviously, the gem is installed already. However, I get this error:

FATAL: Configuration error Gem::MissingSpecError: Could not find 'chef-email-reporter' (>= 0) among 106 total gem(s) Checked in 'GEM_PATH=C:/Users/P465-B91/.gem/ruby/2.1.0;C:/opscode/chef/embedded/lib/ruby/gems/2.1.0', execute `gem env` for more information
FATAL:   C:/chef/client.rb:10:in `from_string'
FATAL: Aborting due to error in 'C:/chef/client.rb'

I think that need execute this instruction (how documentation says):
/opt/chef/embedded/bin/gem install chef-email-reporter
but in windows is in other way that I do not know

The gem env run:

Any help, thanks.

Looks like you have two rubies on your path. So you are installing it into the first non chef ruby and then the ruby embedded in chef is missing it.

Calling gem install from the absolute path of the chef ruby would indeed fix this. The windows equivilent of /opt/chef/embedded/bin/gem is c:\opscode\chef\embedded\bin\gem.bat

Thanks for your answer @Matt_Wrock, then I must run c:\opscode\chef\embedded\bin\gem.bat install chef-email-reporter ?

4

yes. That should work.

Thanks, I try it.

Any help ?

Apologies for the delayed response. I have seen these ffi-yajl compilation errors on windows myself. I believe it has to do with the way we build chef and I am looking to ensure future versions don’t run into this.

In the meantime I believe you can get “unstuck” by installing the libyajl2 gem and then retrying your original gem install.

Hi @Matt_Wrock, I try to install libyajl2 but it harm the chef-client. I hope you can solve the issues.
