When I make a new Rails project, add gem 'reactive-record', and run rails server, I get a Bundler error: There was an error while trying to load the gem 'reactive-record'. (Bundler::GemRequireError).
What gives? I have Rails 4.2.5 and Ruby 2.1.2.
Cheers!
The latest version of the generator should work very well with the help of Mitch. We collaborated together to make a generator in order to simplify greatly the installation of react.rb and reactive-record.
You should be able to get up and running by adding to your gem file :
gem 'reactive_rails_generator'
Then do a bundle install
and finally :
rails g reactrb:install --all
bundle update
Will install you reactrb, reactive-record and reactive-router.
Once installed, you can create components by doing :
rails g reactrb:component Home::Show
I worked around the problem like this:
Set rvm to use Ruby 2.2.2 and Rails 4.2.4.
Download https://codeload.github.com/catprintlabs/reactive-record/zip/master
Edited reactive-record-master/Gemfile to read:
gem 'reactive-ruby'
gem 'opal'
gem 'opal-browser'
gem 'react-rails'
cd reactive-record-master/spec/test_app
bundle install
rails server
This seemed to work.
Then, I made a new Rails 4.2.4 project. Adding only gem 'reactive-record' to the Gemfile resulted in the same error. Then I made the Gemfile read:
gem 'reactive-ruby'
gem 'opal'
gem 'opal-browser'
gem 'react-rails'
gem 'reactive-record'
And voila, rails server works!
Hope this helps someone else.

An error occurred while installing sqlite3 (1.4.0), and Bundler cannot continue.
Make sure that gem install sqlite3 -v '1.4.0' succeeds before bundling.
I tried to install earlier version on sqlite, not working.
Tried one of the solutions from stackoverflow :
gem 'sqlite3', '~> 1.3.6'
getting this error
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command sqlite3,
Please help i'm new in Rails , this is my first project in rails.
Add gem 'sqlite3' to Gemfile in the root directory of your rails project. Then run bundle install and it should install sqlite and make it available to use in your rails project.
Specify git and branch for the gem sqlite3 in your Gemfile should fix the problem.
gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"

cannot load such file — sqlite3/sqlite3_native (LoadError) Ruby on Rails
Replace gem 'sqlite3' with gem 'sqlite3', '~> 1.3.11' which is in Gemfile in the root directory of your rails project. Then run bundle install.

ahaad#Labbaik:~/Desktop/Ruby_Pro/App_demo$ rails server
Could not find gem 'jquery-rails (>= 0) ruby' in the gems available on this machine.
Run bundle install to install missing gems.
Install this gem separately:
gem install jquery-rails
and run the bundle:
bundle install
(or)
Look up your Gemfile, add gem 'jquery-rails' if Gemfile not contain it, then at your terminial, run
bundle install
I have been using the less-rails-bootstrap gem from https://github.com/metaskills/less-rails-bootstrap in my rails 3.1 project.
I want to upgrade to the 2.0wip version of bootstrap and I found a fork with the same name under https://github.com/sgruhier/less-rails-bootstrap
Both version say to install you add gem 'less-rails-bootstrap' to your gemfile.
Well, how is bundler going to know which one to use? What if 20 people had gems with the exact same name?
I guess the bigger question is how to I specify which gem to use?
Bundler will use the one found on http://rubygems.org, which is the one at the first link you posted.
When trying to use an unreleased branch/fork, you should pass the :git option in your Gemfile to tell Bundler to use that git repository:
gem 'less-rails-bootstrap', :git => "git://github.com/sgruhier/less-rails-bootstrap.git"
I'm starting up a new rails app with the latest version of rails (3.1.3). Rails crashes when I try to start up the server. First I fixed this bug, and now I'm getting this one
ruby-debug-base19-0.11.25/lib/ruby_debug.so: undefined symbol: ruby_threadptr_data_type
There's a discussion about this going on here, but I can't make enough sense of it to get things to work.
UPDATE
I updated the version of ruby-debug
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
and have now moved on to this error
linecache19-0.5.12/lib/trace_nums19.so: undefined symbol: ruby_current_thread
Ok, it turns out that both ruby-debug and linecache needed to be manually updated to the latest versions. These lines in my gemfile did the trick
gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'
To run specs, you need to run bundle exec rspec -d spec
At last I found the problem. The debugger in RubyMine starts without bundle exec, so it doesn't use linecache19 from git. You need to install it manually.
Resolution of the problem found here: http://youtrack.jetbrains.com/issue/RUBY-9418?projectKey=RUBY
gem uninstall linecache19
gem uninstall ruby-debug-base19x
curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem
gem install ruby-debug-base19x –-pre
Make sure to uninstall all linecache19 and ruby-debug-base19x!
The following lines worked for me:
gem 'linecache19'
gem 'ruby-debug-base19x'
gem 'ruby-debug19', :require => 'ruby-debug'
(Hat tip to declan. His comment didn't work for me, but it gave me the idea to add linecache19.)
after trying all advise on stackoverflow, the following combination worked for me
gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'
I'm running Rails 3.1.3 on Ruby 1.9.3-p0 with RVM
when I set :require => 'ruby-debug' the server would not start.
It's repost from this
I also ran into this, and found the solution in Ruby 1.9.3 and ruby-debug. You need to install not-yet-officially-released versions of ruby-debug-base19 and linecache19. The currently released versions indeed cause the exception you had.
Use this gist.
#To install ruby-debug on Ubuntu ruby-1.9.3 you need to download from http://rubyforge.org/frs/?group_id=8883
linecache19-0.5.13.gem
ruby_core_source-0.1.5.gem
ruby-debug19-0.11.6.gem
ruby-debug-base19-0.11.26.gem
#Then in your console
export RVM_SRC=/your/path/to/ruby-1.9.3
# Note, your source path should be something like /home/user/.rvm/src/ruby-1.9.3-p0
gem install archive-tar-minitar
gem install ruby_core_source-0.1.5.gem -- --with-ruby-include=/$RVM_SRC
gem install linecache19-0.5.13.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug19-0.11.6.gem -- --with-ruby-include=/$RVM_SRC
I tried it and it's work!
This is solve of our problems.
I was trying to use fancy-buttons gem in my rails 3 app but now I can not even start my local server because of this error:
$:~/rails/project$ rails server
/usr/lib/ruby/gems/1.8/gems/fancy-buttons-1.0.6/lib/fancy-buttons.rb:1: uninitialized constant Compass
(NameError)
This is what my gemfile looks like:
gem "fancy-buttons"
gem 'haml'
gem 'haml-rails'
gem 'compass', ">= 0.10.6"
I've ran bundle update and bundle install
Using haml (3.0.25)
Using compass (0.10.6)
Using fancy-buttons (1.0.6)
How can I fix this?
Compass needs to come before fancy-buttons in your gemfile. This ensures that it is loaded before fancy-buttons tries to require it as the gems in your gemfile are loaded in order.
