'gem install god' fails with NotImplementedError: C extensions are not supported #248

Open jpa57 opened 7 years ago

jpa57 commented 7 years ago

Our application is a JRuby application, and something about the way it is configured causes this to occur. I can install god in a Ruby 2.3.3 / Rails 4.2 app without issue. Jruby 9.05 and 9.01 / Rails 3.2 however, gives me the "C extensions" error on OSX and CentOS.

My objective is to automatically start Resque servers in production, and I don't like the other options, so I'm hoping someone can suggest a workaround or configuration option.

Here's the output. It deletes the ./siteconf.*rb on each run and the filename is unique as well:

Just stumbled upon this, too, and I think God might have been written with only MRI in mind. Would still be nice, @mojombo, to know whether JRuby is considered in-scope by you or not?
