Question

I have both ruby 1.8.7 and 1.9.2 installed on my system. I have a rails project that I initially built with ruby 1.9.2; but because I heare 1.8.7 is faster, I am trying to switch and finish it using ruby 1.8.7. However, whenever I run certain commands, right now its Rails g, I get the following output in my terminal:

    C:\Users\Edu\workspace\tasks>rails g

From reading other problems, it has to do with 1.8 not understanding some of the syntax of rails 3.1. My question is, are there any resources for getting this resolved? I really like to added speed of 1.8.7 in my development and testing of apps. if not, are there any other suggestions to speed up my development?

Answer 1

You (or someone else) has generated the application using Ruby 1.9. This means that it is using the new-to-1.9 variant of hashes (key: value) rather than the 1.8 version (:key => value).

You will need to update this to be the latter inside config/initializers/session_store.rb if you want to use this application on 1.8.7.
