rake snorby:setup

[MSTRFiNiX]

the file /usr/lib/ruby/vendoer_rubybundler/constats.rb has some errors when I run "rake snorby:setup"
the errors are
"* Starting the Snorby worker process.
/usr/lib/ruby/vendor_ruby/bundler/constants.rb:2:in <module:Bundler>': uninitialized constant Bundler::RbConfig (NameError) from /usr/lib/ruby/vendor_ruby/bundler/constants.rb:1:in <top (required)>'

from ruby:0:in `require'
[X] Error: Unable to start the Snorby worker process."
this is the file context
"module Bundler
WINDOWS = RbConfig::CONFIG["host_os"] =~ /(msdos|mswin|djgpp|mingw)/
FREEBSD = RbConfig::CONFIG["host_os"] =~ /bsd/
NULL = WINDOWS ? "NUL" : "/dev/null"
end"
I use rvm and wondering if that is the problem of this error.
