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"

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.
I am trying to use this fork of a gem:
https://github.com/hoyaemt/capistrano-syntax-checking
In my gemfile I have:
gem "capistrano-syntax-checking", :git => "git://github.com/hoyaemt/capistrano-syntax-checking.git"
When I run bundle install, I get:
Could not find gem 'capistrano-syntax-checking (>= 0) ruby' in git://github.com/hoyaemt/capistrano-syntax-checking.git (at master).
Source does not contain any versions of 'capistrano-syntax-checking (>= 0) ruby'
I have read a bunch of postings but nothing I try seems to work here. Any ideas?
thanks
Joel
The original version is missing the gemspec file. It may be missing other things but I was able to get the bundler to run.
Add a gemspec file to the root of your fork. See here for a simple example and just create capistrano-syntax-checking.gemspec file.
Arg, looks like this is a fairly common problem but I can't seem to figure out how to get my debugger working. I've installed a myriad of gems to try to get this bad boy running but no luck. Here is a list for completeness. I've included my gemfile as well. As is probably quite obvious I'm a RoR newb. I'm using RubyMine as my IDE and upon trying to debug I get an error that states "The gem ruby-debug-base19x required by the debugger is not currently installed. Would you like to install it?". Of course, upon saying 'yes' to download the mirror is broken and the download fails resulting in the following error:
5:56:46 PM Error running Development: SponsorBid: Cannot start
debugger. Gem 'ruby-debug-ide' isn't installed or its executable
script 'rdebug-ide' doesn't exist.
Even though this question duplicates two other questions here, I'll answer it for the sake of completeness.
In order to debug from RubyMine you must use only 2 debug gems:
ruby-debug-base19x
ruby-debug-ide
Exactly these gems must be used, not ruby-debug-base19, not ruby-debug19, not debugger . All the other debug gems must be uninstalled and removed from the Gemfile.
See this answer for the details how to install proper debug gem versions. If you have a problem downloading linecache19-0.5.13.gem gem, try this mirror instead.
Verify with gem list that you have the following or more recent versions installed:
ruby-debug-base19x (0.11.30.pre10)
ruby-debug-ide (0.4.17.beta9)
No other debug gems should be listed by this command.
As stated in another answer, debugger gem must not be used, it will conflict with the debug gems used by RubyMine and debugger will not work. You must uninstall this gem, remove it from the Gemfile and ensure that your code doesn't call any methods from this gem and is not trying to load it.
Happy debugging!
As suggested by #Anjan, your Gemfile for debugging can look like this:
gem 'linecache19', '>= 0.5.13', :git => 'https://github.com/robmathews/linecache19-0.5.13.git'
gem 'ruby-debug-base19x', '>= 0.11.30.pre10'
gem 'ruby-debug-ide', '>= 0.4.17.beta14'`
Just run bundle install to get the proper versions of the required debug gems.
This is what I used in my Gemfile to install the required gems through bundler:
gem 'linecache19', '>= 0.5.13', :git => 'https://github.com/robmathews/linecache19-0.5.13.git'
gem 'ruby-debug-base19x', '>= 0.11.30.pre10'
gem 'ruby-debug-ide', '>= 0.4.17.beta14'`
No manual gem installation required and will automatically work on your fellow developers' computers.
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.
After a bundle update, I want to rollback some gem versions to a specific one. I've tried several options, but I can't do it.
Say I want to use arel in its 2.0.9 version. I did the following:
sudo gem uninstall arel -v 2.0.10
Then in the Gemfile:
gem 'arel', '~> 2.0.9'
And then:
bundle update
Then I get:
Installing arel (2.0.10)
I also tried with gem cleanup and deleting Gemfile.lock, but no.. I allways get the same arel 2.0.10 installed. Am I missing something? Thank you very much!
You're telling it to install any patch version greater than or equal to 2.0.9. If you want to specifically install that version just do this:
gem 'arel', '2.0.9'
