Trying to install a new gem into a rails app and regardless of whether I add or remove a gem from the Gemfile, when I run bundle install, I get the following error:
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 3.0.0) ruby depends on
bundler (~> 1.0.0) ruby
Current Bundler version:
bundler (1.3.5)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
I am confused, because ~> 1.0.0 means that I have to have a version of bundler equal to or greater than 1.0.0 but less than 2.x.x. I'm fulfilling this requirement, so why is it failing?
Just to add, if I leave the Gemfile as is, bundle install works just fine.
UPDATE
Clearly, I misunderstood the ~> symbol. You can look at the checked answer below for an explanation, or an even more in depth one at Meaning of tilde-greater-than (~>) in version requirement?
Actually ~> 1.0.0 is equal to >= 1.0.0 && < 1.1, so 1.3.5 doesn't match. You need another bundler version.

Your solution is actually in the error message that you are getting. Run
gem install bundler
to install the latest version of bundler (that should satisfy the constraints
You can also specify a particular version of any gem by specifying the version flag. For example.
gem install bundler -v 2.2.0
gem install bundler --version 2.2.19 --default

Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.2.11.3) was resolved to 4.2.11.3, which depends on
bundler (>= 1.3.0, < 2.0)
Current Bundler version:
bundler (2.3.12)
Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:2.0.0.pre.3` and rerun bundler using `bundle _2.0.0.pre.3_`
What do gem install bundler:2.0.0.pre.3 and bundle _2.0.0.pre.3_ command gonna do. Are they gonna replace my 2.3.12 and install 2.0.0
There can be multiple versions of the same gem installed in your gemset. Run this:
gem install bundler:2.0.0.pre.3
and then run this:
gem info bundler
you will find two versions of the gem installed. By default, it will run bundle with the latest version but as your gems are not compatible with it you can run bundle with a different version of the gem. To do that you need to run:
bundle _version_
in your case it will be:
bundle _2.0.0.pre.3_
You can also remove the other versions of the bundler gem and just keep the one that is compatible. To remove a specific version you could do:
gem uninstall bundler:2.3.12
When trying to run 'bundle install', I have this message :
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 5.0.2) was resolved to 5.0.2, which depends on
bundler (>= 1.3.0, < 2.0)
Current Bundler version:
bundler (2.1.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (>= 1.3.0, < 2.0)', which is required by gem 'rails (= 5.0.2)', in any of the sources.
Bundler could not find compatible versions for gem "pg":
In Gemfile:
pg (= 0.18.3)
jsonb_accessor (~> 1.0.0) was resolved to 1.0.0, which depends on
pg (>= 0.18.1)
Then, I think I need to change my bundler version why is 2.1.2, I would like to change to 1.17.3.
gem list command says :
bundler (default 1.17.3)
but bundle -v command says :
Bundler version 2.1.2
I am using ruby 2.5.1 with RVM.
Do you have any idea how to do so ?
I read that I can use bundle config set but it does nothing.
Bundler installs a binary that gets invoked before your Gemfile is read, so you'll need to remove the version you are using and install the version you want.
You can do this with RVM with the following:
rvm #global do gem uninstall bundler -a -x -I || true
gem install bundler -v '= 1.17.3'
If you hop between projects, you may have to do this a lot, or you can do this:
gem install bundler -v '= 1.17.3'
And instead of using bundle install, use:
bundle _1.17.3_ install
to specify the version of the bundler gem gets used.
I would recommend you look into upgrading Rails, not only to get on a supported version (that has security updates), but it will also allow you to upgrade bundler again.
You need to delete manually the directory on your problematic ruby version: for example if there is a bundler problem with the 2.5.1 ruby version, go to this path:
/Users/YOUR_USER/.rvm/rubies/ruby-2.5.1/lib/ruby/gems/2.5.0/gems/
and delete the bundler directory.
If bundler is in the default specification you also need to remove the bundler associated file on this path:
/Users/YOUR_USER/.rvm/rubies/ruby-2.5.1/lib/ruby/gems/2.5.0/specifications/default
Then you can re-install a specific version of bundler using #Unixmonkey answer
When I type bundle install I got this error. I tried to find solution but nothing solve my case. Please help me.
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.1.8) was resolved to 4.1.8, which depends on
bundler (< 2.0, >= 1.3.0)
Current Bundler version:
bundler (2.0.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails
(= 4.1.8)', in any of the sources.
Bundler could not find compatible versions for gem "rails":
In Gemfile:
rails (= 4.1.8)
animate-rails was resolved to 1.0.10, which depends on
rails
Try to use
gem install bundler -v 1.17.3
bundle _1.17.3_ install
Your bundler gem is too big. You can downgrade for now by changing your gemfile to specify the lower version, and deleting the lock file again.
gem 'bundler', '1.17.1'
Then try these commands in the terminal
gem install bundler -v 1.17.1
gem uninstall bundler -v 2.0.1
bundle update --bundler
bundle install
That last install command might be redundant. I'm on my phone so I can't test anything unfortunately.
Best of luck!
EDIT:
This is now a Heroku issue. Got it. Heroku docs regarding Bundler
Libraries
The following libraries are used by the platform for managing and running >Ruby applications and cannot be specified. For application dependency resolution and management, bundler is installed based on the contents of your Gemfile.lock. If you have a BUNDLED WITH in your Gemfile.lock then you will receive a different version of Bundler:
Applications specifying Bundler 2.x in their Gemfile.lock will receive bundler: 2.0.1
Applications specifying Bundler 1.x in their Gemfile.lock will receive bundler: 1.15.2
Applications with no BUNDLED WITH in their Gemfile.lock will default to bundler: 1.15.2
For more information on available settings see Bundler configuration. For more information on why we only support a specific set of bundler versions, please see this article about your Bundler version.
So it seems like Heroku only allows certain versions of Bundler to be compatible, relevant doc is linked. Downgrade to 1.15.2 and give it another shot.
You don't need to uninstall the newest version of bundler (especially if you have other applications).
First find the bundler version that you need.
For example, after running bundle install:
Could not find gem 'bundler (>= 1.3.0, < 2.0)', which is required by gem 'rails (~> 4.2)', in any of the sources.
I need any version between 1.3.0 and 2.0. Hence, I would go for bundler 1.9.
Then, install the bundler:
gem install bundler -v 1.9
Run that bundler version to install gems:
bundler _1.9_ install
I have 2 gems that depend on conflicting versions of hashie (one requires ~> 1.2.0 and the other requires 3.3.1):
Bundler could not find compatible versions for gem "hashie":
In Gemfile:
restforce (>= 0) ruby depends on
hashie (~> 1.2.0) ruby
omniauth (>= 0) ruby depends on
hashie (3.3.1)
I'd like to keep both gems and use the higher version of hashie. Is there a way for me override one of the gem dependencies?
The standard advise is to use the higher version compatible.
I do this way, but I think bundler has a defined command for it.
First remove the line of gem 'omniauth' at your Gemfile. Run bundle install, then you must add again the line with gem 'omniauth' to your Gemfile, run bundle install again.
If you look at Gemfile.lock, this install hashie 2.0.5, the higher compatible.
Edit: why does this work?
First I check omniauth dependencies with hashie: hashie < 4, >= 1.2, then the same with restforce: hashie < 2.1, >= 1.2.0. At this point, I know that any version of hashie between 1.2 and 2.0.x must work. Then we must to remove the constraint at Gemfile.lock of continue using hassie 3.3.1, removing 'omniauth' from Gemfile it's done. After that, when install restforce, the bundler find the new version compatible with restforce '2.0.5'. And when you add again omniauth bundler don't update dependencies that are accomplished.
I think bundle update is actually what you were after. That sorts out dependencies and installs different versions of gems if required, giving you the most up-to-date gems possible.
Be careful however, as updating gems can introduce compatibility issues.
