Syntax error in Rails server with wash_out

Question

I'm trying to build a SOAP service with Ruby on Rails 3. After a lot of research I found Wash_out .

Now, when I add the gem to my gemfile, like this:

gem 'wash_out'

My rails application no longer starts, I mean, when I type 'rails s' it gives me an error with wash_out.

/usr/lib/ruby/gems/1.8/gems/wash_out-0.6.1/lib/wash_out.rb:3:in `require':     /usr/lib/ruby/gems/1.8/gems/wash_out-0.6.1/lib/wash_out/dispatcher.rb:19: syntax error, unexpected '\n' (SyntaxError)

I'd appreciate any help, thank you very much.

Answer 1

wash_out requires Ruby 1.9 . Your backtrace shows Ruby 1.8.

Answer 2

From your trace log I'm assuming you're using ruby 1.8 and a short reading of the gem's github shows this:

Rails >3.0 only. MRI 1.9, 2.0, JRuby (--1.9).

Ruby 1.8 is not officially supported since 0.5.3. We will accept further compatibilty pull-requests but no upcoming versions will be tested against it.

So, if you want to use the gem with 1.8 support it'd be wise to lock the version to anything under 0.5.3 . Try setting your gem version in your Gemfile to something under that version and it will probably work but like they say, it's not guaranteed.
