In a Rails 4 app, I am trying to use ActiveAdmin 1.0.pre2. bundle install doesn't complain and seems to have included the gem and it works properly.
I am having this in my gem file:
gem 'activeadmin', github: 'gregbell/active_admin'
$> bundle show activeadmin
/home/aslam/.rvm/gems/ruby-2.1.0#monaeo/bundler/gems/active_admin-3fb7f03335b1
Even after running bundle install several times, I keep getting the following error:
git://github.com/gregbell/active_admin.git (at master) is not yet checked out.
Run `bundle install` first.
I am using
Bundler version 1.6.0.rc2 (upgraded from 1.5.3)
Ruby: ruby 2.1.0p0 (2013-12-25 revision 44422) [i686-linux]
Rails: 4.0.4
I am not sure what is going wrong here?
Try to install a prerelease version of Bundler:
gem install bundler --pre
It should solve the problem.
Use following in the Gemfile
gem 'activeadmin', :git => "git://github.com/gregbell/active_admin.git"
This way when you run bundle install, activeadmin would be sourced from its github repository.
Two things
A. You need to include like this in the gem file since 0.6.x is stable and maintained.
gem 'activeadmin', github: 'gregbell/active_admin', branch: '0-6-stable'
B. You can give a try by forking from the stable version of activeadmin
My solution:
rake rails:update:bin
bundle install

I am a beginner at Rails and when I typed in 'rails server' in Terminal, I received this error:
Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).
I am using OSX Yosemite 10.10.5. I've tried installing it:
gem install mysql2
It still gave me the same error. I see that mysql2-0.4.0 is installed. Please help, thank you!
There is a bug in Rails 4.2.4 and previous, with the newly released 0.4.0 version of the mysql2 gem -- one part of Rails will accidentally refuse to use the newly released 0.4.0 version of mysql2.
The issue is reported here, although without a lot of details:
https://github.com/rails/rails/issues/21544
Until a new version of Rails is released that fixes this one way or another, add this to your Gemfile, specifying that mysql2 0.4.0 won't work:
# mysql 0.4.0 does not work with Rails 4.2.4
# https://github.com/rails/rails/issues/21544
gem 'mysql2', '>= 0.3.13', '< 0.4.0'
You previously probably just have gem 'mysql2' in your Gemfile -- add the version constraints as above, so it knows 0.4.0 won't work. Add the comments so you know why you did it, and can remove it later when no longer neccesary (probably whenever Rails 4.2.5 comes out).
Edit the Gemfile in your app like above, and then run bundle update mysql2 in your app directory, so your app will be using a mysql2 gem version 0.3.x again, as current Rails version wants.
When Rails 4.2.5 or later comes out and you upgrade to it, you will probably want to go back to your Gemfile and remove the version requirement specification for mysql2, return it to saying just gem 'mysql2' again. So your app will be willing to use the newer mysql2 0.4.0 gem, once Rails is willing to do so too.
add gem 'mysql2' to your Gemfile to specify the gems you want to use in your project
run bundle install which will install all gems, specified by Gemfile
run rails s should work fine
I am guessing that this answer has been already answered somewhere but I was not able to find it. I am having troubles with installing Rails 4. I have put in the Gemfile:
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'
And I have run bundle install --path vendor/bundle and all the gems are installed, but when I run bundle exec rails s then I receive an error:
bundler: command not found: rails
Install missing gem executables with `bundle install`
which rails doesn't returning anything. I am using ruby 2.0.0 and rvm and it seems everything has been set up.
What am I missing and how to set-up Rails 4?
What solved my problem for Rails 4, in this case, was running a command in the root directory of the application:
bundle exec rake rails:update:bin
After that , running a bundle exec rails s reported no errors and was working as expected.
In Gemfile please add
ruby 2.0.0
or
Try to use .ruby-version and .ruby-gemset.

I am trying to use the rails gem Kaleidoscope and I'm having some trouble getting it installed. For reference here is the github site: https://github.com/JoshSmith/kaleidoscope
I include it in the Gemfile and it bundles just fine. But it does not install the config/initializers/kaleidoscope.rb.
I then tried to gem install directly, but it keeps telling me that
$ rails generate kaleidoscope:install
Could not find generator kaleidoscope:install
Does anyone have any ideas to help get it working?
Change your gemfile entry for the kaleidoscope gem to this:
gem 'kaleidoscope', :git => "https://github.com/JoshSmith/kaleidoscope"
The run
$ bundle update
This solved the issue on a Rails 4 app just now for me.
I have a Rails 4 project and use activerecord-sqlserver-adapter. The readme installation suggests:
gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter', '~> 4.0.0'
However, bundle install returns:
Resolving dependencies...
Could not find gem 'activerecord-sqlserver-adapter (~> 4.0.0) ruby' in the gems available on this machine.
rubygems.org show the latest version as 3.2.12. How can I bundle install version ~> 4.0.0 as 3.2.12 only supports ActiveRecord 3.x?
Why not just Source version 4.0.0 of activerecord-sqlserver-adapter directly from Github.
In Gemfile
Replace
gem 'activerecord-sqlserver-adapter', '~> 4.0.0'
With
gem 'activerecord-sqlserver-adapter', '~> 4.0.0', :git => "git://github.com/rails-sqlserver/activerecord-sqlserver-adapter.git"
They have not provided support for Rails 4 yet, you can try below gem to obtain same thing.
sudo gem install sic-activerecord-sqlserver-adapter
This will work with Rails 4 definitely, i have tried this. thanks.
It says that the adapter is missing.
You should install ruby-odbc and it should work.
gem 'ruby-odbc', '0.99995'
Gemfile
gem 'rails', '4.0.0'
ruby '2.0.0'
I am using rails 4 but some how, rake 10.1.1 is installed. So, whenever I fire a command like
rake db:migrate
It is giving following error:
rake aborted!
You have already activated rake 10.1.1, but your Gemfile requires rake 10.1.0. Using bundle exec may solve this.
I don't want to write bundle exec each time I fire rails commands.
So, any nice solution for this??
Thanks for your interest
Actually,
gem uninstall rake -v 10.1.1
and then
bundle install
Works for me. Thanks Ju Liu.
You could use
gem uninstall rake
and remove the newer version of the gem.
Or add the current version as a binstub with
bundle exec rake rails:update:bin
bundle binstubs rake
After that, you can use
bin/rake db:migrate
Simply run:
bundle update
Done!
