I am using ruby version 2.2.0p0 and rails 4.2. Any help would be appreciated.

Here is the code that's throwing the error:

# File 'lib/spring/env.rb', line 35

def tmp_path
  path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))
  FileUtils.mkdir_p(path) unless path.exist?
  path
end

Looks like you have XDG_RUNTIME_DIR set to /run/user/gui/ but the server doesn't have write access to that directory. So you can either grant access to that directory, or unset XDG_RUNTIME_DIR by typing unset XDG_RUNTIME_DIR
