Question

I’m trying to install the Rails environment on my brother’s computer so that we can collaborate on my app.

I think I’ve installed everything correctly, but now I’m running into major problems, I think because he’s got a Windows computer. Basically, although everything is (I think) installed correctly, rails server won’t run, because it produces the following errors:

It complains that there’s a problem with

Ruby187/lib/ruby/gems/1.8/gems/activesupport-3.2.8/lib/active_support/dependencies.rb:251:in 'require':

Then points to this file.

config/environments/development.rb:3: syntax error unexpected ':', expecting '}'

It also complains that that line has an

odd number list for Hash (SyntaxError)

That line is

config.action_mailer.default_url_options = { host: "localhost:3000" }

More importantly, that line works just fine on my Mac. The error goes away when I delete it. (But I don’t want to delete it, and I especially don’t want to delete the next one). Same with this error

Ruby187/lib/ruby/gems/1.8/gems/activesupport-3.2.8/lib/active_support/dependencies.rb:245:in 'load':

of this line in my session_store initializer file:

<appname>::Application.config.session_store :cookie_store, key: '_<appname>_session'

Any idea what’s going on?

Answer 1

You are using Ruby 1.8.x but the key: "value" syntax is introduced in 1.9.x

{ host: "localhost:3000" }

Should be written as

{ :host => "localhost:3000" }
