Just upgraded to latest version of mailer and am now getting an error while running

[jbehrends]

Running on CentOS 7.1
Sensu v0.22.1

I was use a previous version of mailer on my sensu server without issue. I just upgraded to the latest version on Github and am now running into an issue which has something to do with the erubis gem.

I see the following error anytime sensu tries to send an email using the latest mailer handler:

"/usr/local/share/gems/gems/mixlib-cli-1.5.0/lib/mixlib/cli.rb:191:in `parse_options': invalid option: --json_config (OptionParser::InvalidOption)

from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require'
from /etc/sensu/handlers/mailer.rb:20:in `<main>'"

Like I said, this was working fine on a previous version. But for the curious, this is how the handler is getting called:

"command": "/usr/local/bin/handler-mailer.rb --json_config jbehrends",

So to try and track down what was causing the issue, I tried commenting out all references to the "erubis" gem, and once I did that the handler actually ran. Although it no longer did anything, it at least ran.

These are the gems I have installed on my system:

$ gem list
