Using ActiveSupport in Ruby 1.9.2 fails - ruby-1.9

I am requiring ActiveSupport in a Ruby script like so:
require 'rubygems'
require 'active_support/core_ext/hash'
to use some_hash.with_indifferent_access.
In Ruby 1.8 that worked fine but Ruby 1.9 throws the following exception:
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- active_support/core_ext/hash (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from backup.rb:3:in `<main>'
What is the correct way to do this in Ruby 1.9.2?

Ran into this same issue with ruby 1.9.2 and activesupport 2.3.5. Ran gem update activesupport, updated to 3.2.9, and the issue went away.

First, Ruby 1.9 includes rubygems already, so you don't need to include that.
Secondly, this works fine for me under Ruby 1.9.1 and Ruby 1.9.2 with ActiveSupport 3.0.3. Are you sure that you have the activesupport gem installed properly under the same Ruby environment that you are testing with? (Perhaps ruby --version and gem list might show something awry.)

Bundle exec doesn't work

I am trying to use rails-erd. The last time I used it was in February and worked fine
I tried using erd and bundle exec erd
I am getting this error.. I have rails 4 in another project, but in this project I use rails 3.2.15 in the gem file
Loading application in 'my_app'...
WARN: Unresolved specs during Gem::Specification.reset:

WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
Failed: Gem::LoadError: You have already activated activesupport 4.0.0, but your Gemfile requires activesupport 3.2.15. Using bundle exec may solve this.
What does this mean and how do I solve this?
The error shows that you have already activated activesupport 4.0.0 but in your gemfile.lock file the version of the activesupport is 3.2.15.
So simply delete the gemfile.lock file and again bundle install
It will take the latest version of activesupportor, or either you can change the version manually.
In the Gemfile of the app specify the version of Rails if you haven't done so:
gem 'rails', '3.2.15'
Run bundle install then try running the script again using bundle exec.
If it still doesn't work try uninstalling rails 4 and then running it.
gem uninstall rails
Ideally if you're executing your script with bundle exec it always execute the script in the context of the current bundle using the Gemfile.

Rake gems:install yields error when following declarative authorization Railscast

I'm following Railstcast #188 to get declarative authorization running on my Rails 3 app (using Ruby 1.9.2) and am running into an issue getting the gem to install.
Ryan suggests adding it in config/environment.rb with the following:
config.gem "declarative_authorization", :source => "http://gemcutter.org"
Then install it with sudo rake gems:install.
However when I try that I get an error:
/Users/Travis/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems.rb:314:in `bin_path': can't find gem rake ([">= 0"]) with executable rake (Gem::GemNotFoundException)
I tried rake gems:install, but got this error:
Don't know how to build task 'gems:install'
The instructions to install declarative_authorization at GitHub recommend a different process, which I also followed but still couldn't get past rake:gems install.
Does anyone know what may be happening so I can get around this?
UPDATE: Here's what my config/environment.rb looks like:

Not sure how your environment is set up, but simply installing rake should do it. If you provide more detail (rvm, bundler, etc.) it may be of help.
gem install rake
Upon further inspection of your path, I see you're using RVM. If your paths are installed properly, you can either use the RVM Global gemset, execute the line above.
Another suggestion I have is checking out the CanCan railscast as that is the bigger norm for authorization these days, more supporters as well.
http://railscasts.com/episodes/192-authorization-with-cancan
"A few episodes ago we covered Declarative Authorization. While it is an excellent authorization plugin for Rails it can be a little heavy for simpler sites. After writing the Railscast on Declarative Authorization Ryan Bates looked for an alternative solution and, failing to find one that suited his needs, decided to write his own, CanCan." - RBates
After seeing your environment, let's try to separate the environments a little. Do this.
rvm gemset create some_other_name
rvm gemset use some_other_name
bundle install
See if this isolates your environment enough.
EDIT: I don't use rake gems:install anymore. You have bundler installed, and I'm assuming you want to use it. I do use rails g gemname:install when the documentation for such exists, I'm going to look at the railscasts again and see what rbates is telling you.
On the CANCAN github page, it says: In Rails 3, add this to your Gemfile and run the bundle command.
gem "cancan".

NOOB capybara Rspec warning: regexp match /.../n against to UTF-8 string

I have the following error when I use capybara with Rspec:
/Users/imac/.rvm/gems/ruby-1.9.2-p180#hbg_3.0.7/gems/rack-1.2.3/lib/rack/utils.rb:16: warning: regexp match /.../n against to UTF-8 string
.
After looking at the posted problem on github they suggest upgrading to rack 1.3.0.
I tried to do that but this is the problem:
If I add the rack gem to my gemfile and then do bundle install I get:
You have requested:
rack = 1.3.0
The bundle currently has rack locked at 1.2.3.
Try running `bundle update rack`
And if I try to do bundle update rack I get:
Bundler could not find compatible versions for gem "rack":
In Gemfile:
rspec-rails (= 2.6.0) depends on
rack (~> 1.2.1)
rack (1.3.0)
How can I update rack so that I can get rid of the error messages>
Thank you in advance.
I searched in google this such problem and found you question))
To solve - install gem "escape_utils"
Then create file RAILS_ROOT/congif/initializers/escape_utils.rb with code:
module Rack
module Utils
def escape(s)
EscapeUtils.escape_url(s)
end
end
end
and enjoy)

git push heroku failing because trying to install development gems. BUNDLE_WITHOUT command not working

I get an error after issuing the git push heroku command. This initially looked like something to be solved by using the heroku config command to bundle without the development:test gems. However, I used that command as discussed in this similar writeup [ Heroku's trying to install development gems even after I've told it not to ] and it still doesn't work.
The line "Using --without development:test" in the push message below seems to indicate the BUNDLE_WITHOUT config command worked, so maybe this is a gemfile or other issue?
Thanks!

Well, the problem is clearly with the autotest-fsevent getting loaded when you push to Heroku, which is not Darwin-based. Although you do have a conditional following the gem 'autotest-fsevent' statement, the gem is still trying to load when you deploy to Heroku. There are two likely causes for this.
The first, is that another gem is requiring it. If nothing else, autotest-growl should also be Darwin-only. I'm not sure these are related, but I'd still double-check.
The next issue is to make sure that Gemfile.lock isn't getting pushed. If you last ran bundle install on Darwin, it's possible that the gem got locked into the dependencies that way. git rm Gemfile.lock before you commit and push to Heroku.
Finally, my favored solution is not to use autotest. I'm not sure if that's an option for you, but I found it to be annoying when I did use it I use RSpec and Cucumber. I realize this last suggestion is a non-answer, but I don't like including platform-dependent gems even in testing, just because when you go to staging, little annoyances like this have a tendency of cropping up.
I'm not sure why Rails Tutorial is still using ZenTest and autotest, I don't know anyone who does... that might be changing, a friend went to the Rails Tutorial session at RailsConf and said Michael was actually noting errata during the tutorial, so maybe it'll be different in a future version.
As a final note, out of curiosity, if you are on OS X, how did you install Ruby? It's in a very odd place.

Is the current Rails 3.0.5 and Bundler dependency set wrong?

On Windows 7 with Ruby 1.9.2-p180 and Rails 3.0.5 installed, if I
rails new trytry
cd trytry
bundle install
it will show
C:\ror\trytry>bundle install

from c:/Ruby192/bin/bundle:19:in `<main>
only after a
gem install bundler
or probably a
gem update bundler
then the bundle install will work. So looks like the Rails 3.0.5 needs a newer bundler which was not listed correctly in the dependency? Otherwise when I gem install rails for 3.0.5, it should have updated bundler as well, is that right?
You've got an older version of Bundler installed, you will need to run gem install bundler to update it to the latest version.
Rails depends on a version of Bundler matching the dependency version of ~> 1.0. If you've got a version of Bundler installed, such as 1.0.0, the process of gem install rails sees this dependency is matched already and so won't update Bundler. Therefore, you need to run gem install bundler to update it to the latest version.
