rails gemfile 'block in setup'

I'm using rails 3.1 and have specified to get the latest annotate gem from github in my gemfile

gem 'annotate', "~> 2.4.1beta", :git => 'git://github.com/ctran/annotate_models.git'

I've run bundle install but when I run annotate to annotate my models I get the error...

`bl开发者_StackOverflowock in setup': You have already activated annotate 2.4.0, but your Gemfile requires annotate 2.4.1.beta1. Consider using bundle exec. (Gem::LoadError)

I'm still to get my head around how gems are updated etc so any advise on how to resolve this would be great. I've tried bundle exec but I get a 'wrong number of arguments' error.

Thanks! Mark.

I don't know what is your annotate command but you should try

prompt> bundle exec {your annotate command with its args}

you can do this:

Try to uninstall rack with

gem uninstall annotate 

and when ask you about your annotate version, select 2.4.0

and run

bundle install
