Can't install into Rails 3 project

[jamie]

I'm trying to add this to a Rails 3 project to start a Rails 4 upgrade, and ignoring #9 it won't even bundle. It seems ten_years_rails says it requires actionview for something, and that was only introduced as a standalone gem with rails 4 so the install fails:

Bundler could not find compatible versions for gem "activesupport":
  In snapshot (Gemfile.lock):
    activesupport (= 3.2.22.13)

  In Gemfile:
    ten_years_rails was resolved to 0.2.0, which depends on
      actionview was resolved to 4.1.0.beta1, which depends on
        activesupport (= 4.1.0.beta1)

    rails (~> 3.2.22.13) was resolved to 3.2.22.13, which depends on
      activesupport (= 3.2.22.13)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

@jamie I think it might be solved in #14. Could you test with that branch?

Also, just curious, what version of Ruby are you using?

[jamie]

I think that #14 doesn't go far enough, it's still got spec.add_dependency "actionview" which will conflict dependencies with Rails 3 eventually. I'll give it a shot this afternoon though.

Currently we're running ruby 2.1, but I want to push for a 2.2 upgrade since that will give us compatibility through to rails 5.2.

@etagwerker yeah, loading it as gem 'ten_years_rails', github: 'fastruby/ten_years_rails_conf_2018', branch: 'fixes/ruby-2-2-syntax-error' gives me the same thing, actionview pulling in a conflicting activesupport version.

@jamie I guess there are two ways to install ten_years_rails, using your Gemfile and bundler or simply with gem install ten_years_rails -- have you tried with gem install ten_years_rails?

[stoem]

Just warming this up, I used gem install ten_years_rails in a Rails 3 app and it gave me

You have already activated activesupport 5.2.8.1, but your Gemfile requires activesupport 3.2.22.29. Prepending bundle exec to your command may solve this.

I tried with bundle exec and got

can't find executable bundle_report for gem ten_years_rails. ten_years_rails is not currently included in the bundle, perhaps you meant to add it to your Gemfile?

Any tips?

@stoem There's a fork of this gem called next_rails that doesn't have the dependency on activesupport. You might wanna give it a try.

The other alternative is to add ten_years_rails to your gemfile, bundle, and try again.

@etagwerker Thank you, go it. Next_rails works for me.
