Syntax error when trying to start rails server

Question

I'm recently began working on a project which I've cloned from github.

Everytime I try start the rails server I get the following error:

/Users/thomas/.rvm/gems/ruby-1.9.3-p194/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:245:in load': /Users/thomas/Projects/BillingMiddleware/config/initializers/session_store.rb:3: syntax error, unexpected ':', expecting $end (SyntaxError)

My collegue is also working on the project and doesn't seem to have any problems starting the server. He is running the same version of ruby, rails and WeBrick as me.

I've tried changing the syntax from key: to :key =>, this shouldn't be the problem though as I am running ruby version 1.9.3. If I make that change anyhow I get a different error message:

I've tired completely removing and re-installing rvm, ruby and rails several times to no prevail. I've also tried running bundle install which hasn't help.

Does anyone have any idea of what's going wrong?

Thanks

Answer 1

Try changing your hashes to :key => :value syntax. The same error and fixes are discussed at Rails 3.1 Deployment to Heroku Error . The temp fixes suggested are: config/initializers/session_store.rb

App::Application.config.session_store :cookie_store, :key => '_BillingMiddleware_session'

config/initializers/wrap_parameters.rb

ActionController::Base.wrap_parameters :format => [:json]

Answer 2

Looks like hash syntax on another line, after you fixed that one. Check config/intializers/wrap_parameters.rb and i wonder if this project got the flag to "not" use the new syntax?
