So Rails 3.0.1 requires Bundler v1.0.0 - v1.0.22 (actually any 1.0.x version up to, but not including, 1.1.0), but you have a newer version of Bundler that's being loaded when Rails is started. You could uninstall the newer version(s) of Bundler (though this is a crappy way to deal with the issue) or since you're using RVM, just create a gemset for Rails 3.0.1.
$ rvm gemset create rails_3.0.1
$ rvm gemset use rails_3.0.1
$ gem install rails -v 3.0.1
$ rails -v
3.0.1
Note: this requires that Bundler not be in your global gemset for the Ruby version you're trying to use. If the global gemset contains a Bundler version equal to or higher than 1.1.0 then you'll get the same error as before.
Update: A little explanation about ~> and RubyGems versioning might be handy. The section on pessimistic version constraint in the RubyGems docs does a fantastic job of covering everything.
You may need to update to bundler 1.1.4.
gem update bundler
should do the trick.
This is possibly due to Ruby v1.9.2/3 uses bundler v1.1.4 while Rails v3.0.1 requires bundler v~1.0.0. Hence, by simply updating the Rails version to v3.2.6, the conflict is solved. This conflict can be easily solved by matching the Ruby and Rails version.
I had same problem with mysql. I uninstalled mysql gem and I installed the newest version of mysql gem. Is RVM ok?

While attempting to solve another issue identified in this thread:
Error while trying to load the gem 'devise. ActiveSupport: Duration can't be coerced into Integer, I followed the suggested solution and changed my ruby version from 2.4.1 to 2.3.3 using rbenv. I also made similar changes in my Gemfile to reflect the new ruby version. However, when I tried to bundle install again, it throws an error saying that my ruby version is 2.4.1, when my Gem specified 2.3.3. However, running ruby -v shows my ruby version is on 2.3.3.
$ bundle install
Your Ruby version is 2.4.1, but your Gemfile specified 2.3.3
$ ruby -v
ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-darwin16]
Any help here would be appreciated. Thank you!
Gem installation is specific to ruby version, so the bundler you're using is likely installed to your old ruby. Try installing bundler again:
gem install bundler
That should fix your problem.
I am doing a project in Rubymine and I get a notice that I need to install some gems. When I do the bundle install I get the following error:
Gem::InstallError: activesupport requires Ruby version >= 2.2.2. An
error occurred while installing activesupport (5.1.0), and Bundler
cannot continue.
Make sure that gem install activesupport -v '5.1.0'
succeeds before bundling.
Process finished with exit code 5
I am using version 2.4.0 of Ruby, so I do not understand why I get this error.
Thanks for the help!
First check your ruby version.
$ which ruby
/Users/.rvm/rubies/ruby-2.1.2/bin/ruby
$ ruby --version
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
Use the Ruby 2.4 version instead...
rvm install 2.4
rvm use 2.4
Rubymine has nothing to do with this.
As #Sunny commented out you need to make sure the ruby version you are using. I recommend you to create a new file on the app root directory, name it .ruby-version and inside add the ruby version you want ruby-2.4.0 (you can always modify it later and set a different versions).
Also you might want to use a ruby version manager like rvm or rbenv both are good, on my personal preference I use rbenv for development and rvm for production environments. You can follow this guide, feel free to change the OS and the ruby manager as you prefer.
I'm trying to bundle install a ruby project in Git Bash but I'm getting the above message.
ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [i836-mingw32]
gem -v
2.3.0
New to Ruby so its really frustrating. I'm trying to do the project below
http://www.viralrails.com/?p=25
This happens because you are specifying a Ruby version in your Gemfile (2.3.0) and this version is not installed or is not the current or default version.
Don't remove the line ruby '2.3.0' as someone said above. You app may have dependencies to this version. Do the following:
1) Check if you have Ruby 2.3.0 installed. If you are using rvm this may be done by
rvm list
and if you are using rbenv by
rbenv versions
2) If you don't have this Ruby version in your list of installed versions, then install it by issuing the following command
rvm install 2.3.0
and if you are using rbenv by
rbenv install 2.3.0
3) If you already had Ruby 2.3.0 installed or completed step 2 above, enter your app directory and issue the following command
rvm use 2.3.0
and if you are using rbenv by
rbenv local 2.3.0
Then run
bundle install
and I believe things will be ok.
Hope it helps!
Install bundler after installing ruby 2.4.0.
gem install bundler
If you installed bundler before installing ruby 2.4.0 then you should reinstall bundler or update it.
Also if the above command didn't work.
gem update bundler
I'm new to Rails, following Michael Hartl's textbook. When I run $ bundle install I get the following error:
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 3.0.1) ruby depends on
bundler (~> 1.0.0) ruby
Current Bundler version:
bundler (1.7.6)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
I then try $ gem install bundler which works fine:
Successfully installed bundler-1.7.6
Parsing documentation for bundler-1.7.6
1 gem installed
However, this doesn't solve the problem. I'm sensing this has something to do with version problems, but I'm not sure where to go with it...
The following :
In Gemfile:
rails (= 3.0.1) ruby depends on
bundler (~> 1.0.0) ruby
means the version of bundler required is greater than or equal to 1.0.0 but strictly less than 1.1.0. Rails 3 is depending on an old version of bundler. At this point of time, you should try out Rails 4 instead :)
You may read up more about the "version syntax" in http://guides.rubygems.org/patterns/#pessimistic_version_constraint
As #user3927334 has already stated the error you got is due to a version conflict between bundler and rails.
Most likely you have run rails new my_app with an outdated version of the rails gem.
gem install rails -v 4.2.0.beta4
Can be used to install a particular version of Rails. see Installing Rails.
You should then remove your old app and rerun the app generator:
rails _4.2.0.beta4_ new hello_app
If you indent to develop on your local machine I would recommend installing RVM (Ruby Version Manager) (as did previous versions of MH's Ruby on Rails Tutorial.)
It allows you to effortlessly switch between different versions of ruby and different sets of gems.

Here in lies the issue. I've reinstalled ruby. I've installed 1.8.7, 1.9.2, 1.9.3 and still no luck across the board.
i've run
$ gem update bundler
But bundle is 'up to date', so still no luck
I've really poked at this all day now, and with no luck I open my palms to you all.
the issue is that in #global gemset you have higher version of bundler then the one required.
you can either specify the version on command line:
bundle _1.0.27_ exec rails -v
or use Gemfile:
printf 'source :rubygems\ngem "rails", "3.0.1"\n'
rails -v
this assumed you have the gem rubygems-bundler - but it comes by default with RVM so you should have it.
and last - remove bundler from #global:
rvm #global do gem uninstall bundler
but there is one caveat - while reinstalling ruby gem bundler will be installed again.
