I'm attempting to install devise_token_auth. The instructions say to add gem 'devise_token_auth'
to my Gemfile, then run bundle install. I created a brand new API only Rails app, follow the instructions, and get the following:
Bundler could not find compatible versions for gem "rails":
In Gemfile:
rails (~> 6.1.1) x86_64-darwin-20
devise_token_auth x86_64-darwin-20 was resolved to 0.1.21.alpha2, which depends on
rails (~> 4.1.4)
What is x86_64-darwin-20? That's not in the Gemfile, but I'm working on MacOS. What's going on?
Credit to Rockwell Rice:
https://rubygems.org/gems/devise_token_auth/versions/1.1.4 shows you the dependencies.
devise_token_auth depends on rails >= 4.2.0, < 6.1. So I just recreated a new rails app with version 6.0.

Im literaly bumping my head into a wall and I can not find a solution by myself about this problem.
I'm starting a project with Solidus , a Spree commerce fork. I played around with the gem for a litle while and now that I am ready to get serious and start to develop , I create a new project ad I'm bumping into this nasty error :
Bundler could not find compatible versions for gem "rails":
In snapshot (Gemfile.lock):
rails (= 5.1.2)
In Gemfile:
rails (~> 5.1.2)
solidus was resolved to 1.0.0, which depends on
solidus_core (= 1.0.0) was resolved to 1.0.0, which depends on
rails (~> 4.2.0)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
and bundle update is not solving my problem... I am running out of solution and will appreciate some hands in help in how to fix this problem.
Thanks
Bundler is doing you a favor here by showing you that you have incompatible version requirements for the rails gem.
You have rails (~> 5.1.2) listed in your gemfile and the solidus gem has a dependency on rails (~> 4.2.0), so there is a conflict about which version of rails your app should use.
Is there a reason you are using solidus version 1.0.0? It looks like the latest version of solidus is 2.0.2 at present. Later versions of solidus will have a more recent dependency listed for rails, which will allow your application to use rails 5+.
Update the version of solidus in your gemfile to something more recent and see if that allows bundler to install successfully.
I am new to rails and building my first web application using version 4.2.4.
I am trying to install the activeadmin gem using
gem 'activeadmin', '~> 0.6.6'
However, when I run bundle install I get an error which says:
Bundler could not find compatible versions for gem "rails":
In snapshot (Gemfile.lock):
rails (= 4.2.4)
In Gemfile:
activeadmin (~> 0.6.6) ruby depends on
rails (< 4, >= 3.0.0) ruby
rails (= 4.2.4) ruby
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
Is this suggesting that I need to go down a version of rails in order to make this gem work or can I keep 4.2.4 and use the suggested bundle update method without causing any issues with my app and other gems?
The version of activeadmin that your Gemfile specifies does not support Rails 4. From the readme:
We're currently working on 1.0.0, which as far as dependencies, moves
us from meta_search to Ransack and adds Rails 4 & 5 support.
You can get it by tracking master:
gem 'activeadmin', github: 'activeadmin'
Or you can using rubygems:
gem 'activeadmin', '~> 1.0.0.pre2'
Change your Gemfile as shown, and then run bundle install
I'm trying to install a gem, I updated it in the gemfile, then bundle install.
I received the following error message:
Bundler could not find compatible versions for gem "rails":
In Gemfile:
merchant_samples (>= 0) ruby depends on
rails (~> 3.2.9) ruby
rails (3.2.7)
What does it mean? What can I do? I'm using rvm, do I need to switch to another version of ruby? of rails? and if so, which one and how? and why :)
What that means is that merchant_samples gem requires rails 3.2.9 or higher and you are using version 3.2.7. So to use it you need to upgrade your rails version to 3.2.9 at least, but you should actually update to the latest 3.2.* since there are some security issues on older versions. At the moment the newest version is 3.2.13
You can upgrade changing your Gemfile to:
gem 'rails', '3.2.13'
Then you must run bundle and everything should be working.
Trying to test out this awesome looking gem - http://icelab.com.au/articles/welcome-to-the-omnisocial/ - that promises easy integration of Twitter & FB login to my app.
But, when I run bundle install I see this:
Bundler could not find compatible versions for gem "bcrypt-ruby":
In Gemfile:
omnisocial depends on
bcrypt-ruby (~> 2.1)
bcrypt-ruby (3.0.0)
When I specify that I want Bundler to use version 2.1, I get this:
Bundler could not find compatible versions for gem "bcrypt-ruby":
In Gemfile:
bcrypt-ruby (~> 2.1)
rails (= 3.1.0) depends on
bcrypt-ruby (3.0.0)
So now I have to choose between either Omnisocial or Rails 3.1. Seems like such a crappy choice.
What do I do to get it to work?
I've pushed released a new version of the gem (which I've had to rename to omnipopulus for legal reasons). This new release doesn't depend on any particular version of the bcrypt-ruby gem, so you should be fine to run it with Rails 3.1.
Add this to your Gemfile to get going:
gem 'omnipopulus'
Then run bundle and follow the instructions in the README at https://github.com/icelab/omnipopulus
Make sure that you've removed any references to omnisocial in your app.
The current github version of omnisocial requires no particular version of bcrypt. See here.
But they added a dependency to a RC version of Rails...
What I often do in these cases:
clone the github repository
change what I need
run the gem's test suite
if ok, add my own version to the Rails app
if a new version of the gem is released an fit my needs, I use the official version again
While trying to install Rails admin, I added it to my gem file as instructed. I deleted the gemfile.lock
Then I ran bundle install. I got this message:
Bundler could not find compatible versions for gem "rails":
In Gemfile:
rails_admin depends on
rails (~> 3.0.3)
rails (3.0.1)
I am using rails 3.0.1, not really sure I understand the issue? But its obviously stopping me from installing.
Also, if I put rails_admin in the gem file like so:
gem 'rails_admin'
instead of:
gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git'
that seems to install it a version 0.0.0 and then doesn't proceed to do anything (so clearly thats not right either).
Is there a version I can specify that might work?
Thanks!
The issue is that the gem now required rails 3.0.3 and you are using 3.0.1
~> means at least this tiny revision or greater.
E.G. ~> 3.0.3 means 3.0.x where x >= 3
As for what gem version will work on 3.0.1 I do not know.
