I am running into issues when trying to install the activeadmin gem. I am using Ruby 2.0 and Rails 4.0.2.
Here is what I get when I run "bundle install" in my project directory:

Any help would be greatly appreciated in fixing this issue.
The gem you are trying to install requires rails 3.2.* and you are using 4.0. Either downgrade rails or use anther gem.
Use this to install activeadmin for rails 4: Active admin install with Rails 4
gem 'activeadmin', github: 'gregbell/active_admin', branch: "rails4"
You are running the bundle install from windowscmd, while had begun to run it from cygwin shell, try to run from cygwin shell, because I see you have mixed the native windows, and cygwin path styles up.

I was trying to update my rails app from Rails 6.1 to 7.0.4.

I've tried to reinstall bundle and each gems by looking at the dependencies showed here : https://rubygems.org/gems/rails/versions/7.0.4/dependencies.
After many researchs, I coudln't find a way to unlock the situation, each tries leads to the dependencies error showed earlier.
Actionpack and activerecord are bundled directly with rails, so it updates alongside.
simple_token_authentication is dependent on an earlier version of rails, so you need to update it as well.
It appears to be dependent in <5 which is odd considering you say you’re updating from 6.1, but I’ll assume your bundle functioned before.
However, it looks like you’re using the latest version, so your options are to find a different gem or wait for the gem to be updated.
I updated my ruby to 3.0.0 but for some reason now my application doesn't work. I have searched online for different answered but I cannot find anything. This error has gotten me going crazy now. Here is what happens.
When I do bundle update I get:

thredded (~> 0.16.13) was resolved to 0.16.16, which depends on

I looked online and someone said to do bundle update rails but when I do I get this error:

Currently Ruby 3.0 is not supported with Rails, as there will be next release for Rails. You can do following and it works by installing dev branch of ruby 3. I used ruby 3.1.0dev (2021-02-14T05:09:08Z master ff527e7e32) [x86_64-darwin19] Following commands are with RVM you can use same with other softwares I tried by installing
rvm install ruby-head
This command installed version ruby 3.1.0dev Now install rails
gem install rails
Now create new project
rails new test_rails
now run it using rails s' if you are getting error that ruby version 3.1.0 required is because rails has added this in .ruby-version` so it is just warning no issue. You can try latest version but as I said it is dev version not stable. Note ruby-head will keep changing version of ruby installed as it is latest version. And good news it is blazing fast! I love it.
I suggest use ruby 2.7.2 with rails 6 till new release comes, the above is for test purpose only, not production or actual product. You should use ruby 2.7.2 for production or product.
I'm doing this upgrade for the first time and I'm facing problem on very first step :-(
Basically I want to upgrade rails version of my project so I changed my Gemfile for the rails 5.2 and tried to run:

What should I do?
First, as ThorTL67 noted in the comments, it is a good idea to update your Rails version incrementally, not in one big leap. That way, your dependency issues will be less complex.
Check what version of Bundler you are using by running bundle version. If that version is old, it might be that some dependencies are not correctly calculated, and it might help to update Bundler (gem update bundler).
Then to the steps you can take to update from 4.2 to 'some higher version'. The list of errors that you got shows the conflicts between gem dependencies. You can try and tackle these conflicts one by one.
Bundler could not find compatible versions for gem "activerecord":
In Gemfile:
rails (~> 5.2) was resolved to 5.2.1.rc1, which depends on
activerecord (= 5.2.1.rc1)
schema_plus_views was resolved to 0.3.1, which depends on
activerecord (~> 4.2)
This error is pretty straightforward. It tells you that gem rails needs activerecord v5.2.1, but that gem schema_plus_views needs activerecord >= 4.2.0 but < 5.0 (see the RubyGems explanation of constraints). So how to resolve this? If you check the source page for schema_plus_views, you see that there is no compatible version yet for activerecord v5.2.1, and that it is not likely to be there soon: Any plan to update this gem to be compatible with rails 5.2?
So in this case, you have a few options. Leave it out of your Gemfile and remove the dependencies on this gem from your code; check for alternative gems that give you the needed functionality; help to update the gem to support rails 5.
Bundler could not find compatible versions for gem "rails":
In Gemfile:
rails (~> 5.2)
gaffe was resolved to 1.2.0, which depends on
rails (>= 4.0.0)
rails_admin was resolved to 1.3.0, which depends on
rails (< 6, >= 4.0)
rails_admin_globalize_field was resolved to 0.4.0, which depends on
rails (>= 4.2)
sql-logging was resolved to 3.0.10, which depends on
rails (>= 4.0)
I'm actually not sure what the problem is here. These dependencies on the rails gem do not seem to contradict each other, so I would try to find out what gem is the actual problem by commenting them out one by one and then trying the update again. This might give you more information.
Bundler could not find compatible versions for gem "rake":
In Gemfile:
rake (~> 11.2)
capistrano (~> 3.6) was resolved to 3.11.0, which depends on
rake (>= 10.0.0)
derailed_benchmarks was resolved to 1.3.2, which depends on
rake (< 13, > 10)
This also seems like it should not be a problem. I would try to change your rake dependency in your Gemfile from gem 'rake', '~> 11.2' to gem 'rake' and see what happens with the dependency messages.
Chances are that after all these steps, you will get different error messages. You have to tackle them one by one in the same manner. Unfortunately, there is no silver bullet, and updating Rails can be a tedious process, especially when your application depends on a lot of gems. You have to fix this, issue by issue, by removing your own dependencies on gems, helping gem communities with maintenance/updates, or (worst case) forking a gem and changing the code yourself to make it work again for your application. Good luck!
In order to update your dependencies, you can use tools like bummr. Please, be sure to have a good test suite as the README specify. After that, you can start fixing compatibility issues, deprecations and more.
I have installed jruby and trying to use Neo4j for my Rails app. But typing bundle install gives me the following conflict.
Bundler could not find compatible versions for gem "railties":
In Gemfile:
neo4j (>= 2.2.3) java depends on
railties (< 3.3, >= 3.0.0) java
rails (= 4.0.0) java depends on
railties (4.0.0)
Here's my gemfile:
source 'https://rubygems.org'
gem 'rails', '4.0.0'
gem 'sass-rails'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails'
gem 'therubyrhino'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'
group :doc do
gem 'sdoc', require: false
end
gem 'bcrypt-ruby', '~> 3.0.0'
gem 'unicorn'
gem 'capistrano', group: :development
group :development, :test do
gem "rspec-rails"
end
gem "neo4j", ">= 2.2.3"
Should I remove my Gemfile.lock and run bundle update? Thanks!
There is a branch for rails 4 in the neo4j project, so you can just specify it in Gemfile:
gem 'neo4j', git: 'git://github.com/andreasronge/neo4j.git', branch: 'rails4'
That says that the currently available version of neo4j require a version of railties < 3.3, but rails 4.0.0 requires version 4.0.0 of railties: bundler cannot resolve this conflict.
The only way out of this is for neo4j to be updated to work with rails 4.0. It is entirely possible that neo4j's version constraint on railties is a precaution only - there may be nothing more to do than checking that everything still works under 4.0.

Running bundle install yields:
Bundler could not find compatible versions for gem "erubis":
In Gemfile:
rmre (~> 0.0.4) ruby depends on
erubis (~> 2.6.6) ruby
rails (= 3.2.8) ruby depends on
erubis (2.7.0)
I tried commenting out the version numbers and even removing the gems related to asset management. Still, I can't seem to arrive at a combination of gem versions that work here. It's the first time I've run into this sort of situation and I am not sure what else I might do to try out the rmre gem with a version of rails that is at least 3-point-something.
Is there a clever way to search for a workable dependency resolution here? If there is not a gem version configuration that meets the recommended dependencies, is there a least-bad approach to pursue?
Many thanks!
You might try contacting the rmre gem author to see if they would be willing to loosen the dependency restriction, so that it's not tied to such a narrow erubis version. Forward compatibility is part of what gem authors need to maintain if they want their gem to continue to work with the latest versions of rails. – normalocity Nov 2 at 1:31

Worked.
Download the zip file from the page. Then execute the gem command. Worked for me. Incredible program.
