Passenger + Rails running bash commands

Question

I have Rails app, server is Passenger + nginx.
In my code I'm running Slic3r via %x[]. But it doesn't run and doesn't produce any output.
I also print run command there and if I run it in bash or in console it works.
My server is Digitalocean, Ubuntu + I use RVM

P.S.: also trying to use remote debug from RubyMine, but it also doesn't work

should be `%x{}` not [] I think. You can also used backticks or [system](http://www.ruby-doc.org/core-2.1.1/Kernel.html#method-i-system) — j-dexx, May 06 '14 at 14:55
According to "The ruby programming language" book and this http://stackoverflow.com/questions/6338908/ruby-difference-between-exec-system-and-x-or-backticks question it doesn't matter. I think there can be problems with users and permissions — Alex Tonkonozhenko, May 06 '14 at 15:08

The answer wa simple: according to http://blog.bigbinary.com/2012/10/18/backtick-system-exec-in-ruby.html I found that backticks doesn't output STDERR so I just added %x[#{my_command} 2>&1] to capture it
