When I run rails console in my production server with this command
rails c
I get this message:
You must use Bundler 2 or greater with this lockfile.
I checked bundler version:
gem list bundler
And I got this
bundler (2.0.2, default: 1.17.3, 1.16.3)
bundler-unload (1.0.2)
rubygems-bundler (1.4.4)
I read I could set bundler version with this command
bundle _2.0.2_ -v
And I got this message
Bundler version 2.0.2
But I keep getting the same error when running rails console.
Finally, some more information. My Gemfile.lock says I bundled with v2.0.1 (development bundler version). I'm using rvm in production and rbenv in development (not on purpose; I always used rbenv but I inherited an application using rvm in production).
What should I do to run rails console in production server in this situation? Can I uninstall older bundler versions and keep only v2.0.2? Should I updgrade to v2.0.2 in development to have the same versions?
Thanks!

I'm having trouble creating a new Rails app. I'm using a fresh WSL2 + Ubuntu 18.04 install.
Long story short, I followed the Rails installation procedure from https://gorails.com/setup/windows/10 but when installing bundle using gem install bundler, I end up with 2 bundler versions (2.1.2 and 2.1.4).
If I stick with 2.1.2 webpacker throws an error, so I definitely need to install the newest version. The problem is, when I install 2.1.4 the default version remains 2.1.2, so then I go to cd /.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/specifications/default and remove bundler-2.1.2.gemspec, and then I do a gem install bundler --default to get only v2.1.4 as default:
gem list bundler
*** LOCAL GEMS ***
bundler (default: 2.1.4)
But here is the problem; if I run bundler -v I get:
bundler -v
Bundler version 2.1.2
But the real problem is that, when running rails new, it clearly tries to use 2.1.2 which inevitably fails.
How can I solve this?
Thank you
Try gem uninstall bundler --version 2.1.2.
From the app directory run these commands:
gem install bundler
bundle update --bundler
bundle install
This rebuilds the Gemfile.lock with the correct Bundler version.
EDIT: You can create the directory first with rails new my_rails_app, then do cd .. ; rails new my_rails_app after running the above commands.
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.
I'm running Ruby 1.9.3 and Rails 4.0.0, and I'm just starting to learn how to use Ruby on Rails. Whenever I type the command to run the server:
$ rails s
I get this error:
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.0.0) depends on
bundler (< 2.0, >= 1.3.0)
Current Bundler version:
bundler (1.0.15)
So I updated it and then checked the version of the bundler using this command:
$ gem list bundler
And this is the result I get:
*** LOCAL GEMS ***
bundler (1.3.5, 1.3.0)
Although it says this, I still continue to get the error as mentioned above. Anyone know how to fix this? Thanks
You may have to prefix it with bundle exec:
bundle exec rails server
You can check bundler's version using
bundle -v
Prefixing your rails / rake command using bundle exec before will ensure ruby will use the gems required by your application.
bundle exec rails s
so I run:
$ gem install rails --version 3.0.1
Successfully installed rails-3.0.1
1 gem installed
Installing ri documentation for rails-3.0.1...
Installing RDoc documentation for rails-3.0.1...
then I get the error:
$ rails -v

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?
Error message: Bundler could not find compatible versions for gem "spree_core":

When I do rails --version, I get:
git://github.com/shuber/sortable.git (at master) is not checked out. Please run `bundle install`
Have tinkered with the .bashrc profile as suggested by other StackOverflow posts, 'bundle update' gives the same error message as the first one above.
Mac OS X Lion
Rails 3.0.7
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin11.3.0], MBARI 0x6770, Ruby Enterprise Edition 2011.03
'rvm gem list bundler' returns 1.1.3 and 1.1.3 only, on my working environment with this git clone I have bundler 1.1.3 and 1.0.22.
Thoughts? Not really sure what to do at this point. I tried deleting Gemfile.lock and running bundle install again, but no success.
How are you specifying the spree gem in your Gemfile? The error message seems to say you're specifying one version of 'spree' (possibly =0.50.2), while spree_paypal_express is requiring another version (>= 1.0.0).
I'm not too familiar with bundler, so I can't say for certain. Maybe posting your Gemfile can help us find more leads for you?
Good luck!
