13:53 <throstur> I'm working in an environment that runs on jruby, but I want to use ruby gems such as rest-client. How do I install them, since I can't do `gem install rest-client` ?

13:58 <throstur> I try to run the install as root like: `java -jar /var/lib/opsgenie/marid/jruby-complete-9.2.8.0.jar -S gem install rest-client` but it tells me `You don't have write permissions for the uri:classloader:/META-INF/jruby.home/lib/ruby/gems/shared directory`

14:15 <throstur> I also tried `yum install rubygems-rest-client` and then running my ruby script but it gives me a LoadError on loading rest client

15:20 <throstur> Trying to install jruby with the install script seems to be failing, it prints those warnings as documented in jruby #4834 but then there is no more output for at least 10 minutes

15:25 <enebo[m]> throstur: GEM_HOME can be used to install to a separate real file system location. GEM_PATH can be used to add that as an extra dir to look at when loading gems

15:28 <headius[m]> throstur do you need to use jruby-complete rather than a "normal" install?

15:32 <throstur> headius[m] honestly, I don't know, but I believe so. We are using this: https://docs.opsgenie.com/docs/marid-integration-server-for-opsgenie

15:33 <throstur> enebo[m]: if I understand correctly, I can install rubygems, install my gem anywhere, and put export GEM_HOME=<that anywhere place> in /etc/profile.d/gems.sh ?

15:38 <enebo[m]> throstur: well when you run gem install it will put it whereever GEM_HOME is and if you put all the gems you use then just a single GEM_HOME is enough. If you want builtin gems as part of jruby-complete then you need to add this new GEM_HOME to GEM_PATH so it sees both locations

15:48 <throstur> seems like neither is defined on my system. I will put them somewhere... what's a sane or default location?

15:49 <throstur> (when I say my system, I don't mean "my" system but the one I'm working on, please don't think I'm incompetent:D)

15:51 <throstur> I see that yum install rubygems sets it to /usr/lib/gems

15:51 <throstur> I'll just use that

15:52 <throstur> doh, should be /usr/share

16:03 <enebo[m]> throstur I would pick a app-specific directory for those gems

16:04 <enebo[m]> throstur: sharing gem location between C ruby and JRuby is also ill-advised because we have different versions of native gems so a gem install with MRI may not work on JRuby and vice-versa

16:06 <enebo[m]> I don't actually do app development (JRuby development specifically) so I was hoping some other JRuby people will chime in here on best practices

16:06 <throstur> yes, I saw that

16:06 <throstur> I've decided to scrub ruby off the system and only keep jruby for that exact reason

16:06 <enebo[m]> Depending on how you run your system you can also specify the ENV as part of the command-line

16:06 <throstur> lovely centos distributes ruby 2.0.3 :)

16:06 <enebo[m]> GEM_HOME=/opt/myapp/gems java -jar ...

16:07 <enebo[m]> it sounds like you are running within a larger java app so I suspect you may have some envs already needed for running it

16:08 <throstur> thank you for your advice

16:12 <enebo[m]> throstur: np. You are experiencing a tougher rampup than most Rubyists you just rvm install jruby and can start running stuff

16:12 <throstur> heck yeah, writing the code only took a few hours... integrating it into the jruby environment has already taken me the better part of a day
