I'm on Windows and i'm Trying to install The Flat UI Pro which need's Twitter Bootstrap Rails 3.1.
But whenever i try to install The Less Stylesheets, i'm getting a lot of weird errors about therubyracer gem an the V8 file.
I need to run
rails generate bootstrap:install less
which gives me the error
[WARNING] Please install gem 'therubyracer' to use Less.
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/less-2.3.2/lib/less/java_script/v8_context.rb:2:in `require': cannot load such file -- v8 (LoadError)
The server doesn't start also
My Gem File
source 'https://rubygems.org'
gem 'rails', '3.2.13'
gem 'jquery-rails'
gem 'twitter-bootstrap-rails'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'less-rails'
end
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'therubyracer-heroku', :platform => :ruby
end
If someone has experience or has installed Twitter Bootstrap for Rails 3.1 Asset Pipeline before please give me a helping hand :) Thank you
you can not install twitter-Bootstrap with less file on Window machine because , Window does not support twitter-bootstrap-less library l.e ( libV8 , exec.js , python , error) that not work on Window .
if you want to run your project on window machine than used "Bootstrap gem" instead of 'twitter-bootstrap-rails gem' .
Otherwise used the Ubuntu OS it is best suited for any Ruby on Rails Application with solve dependency of your GemFile easily . and you used "less-rails", and "twitter-bootstrap-rails" easily and not come any issue with libV8.

I'm working on a project which I normally work on Mac OSX. I'm on ruby MRI V.1.9.3-p194 and rails v.3.2.8.
but, for the time being, there has been a need to collaborate the project source code with another team member who's using windows.
I proceeded on to set up everything on my colleague's windows machine and almost everything seems to work quite well, the same ruby and rails framework version are used. I managed to get 'bundle install' to pass by having most of their dependencies resolved. (So, you can imagine that the versions of gems have got updated from those on my Mac Machine)
I also have node.js installed on my colleague's machine in order to make ruby able to run javascript.
A while later, it seemed I was able to start the web server using "bundle exec thin start" and it's starting without any error. The other reason, I'm quite sure my setup's been coming in the right way
because I can retrieve model records via rail console beautifully. But I'm only getting one error, every time I try to browse to the app on the web browser.
Every time I'm getting node.js dependency error "cannot find module 'stylus'"
that even prevents me from getting the login page loaded.
here is a snapshot of the error I get:
also, I'm happy to share you my Gemfile, so it could give you more clues what actually goes wrong? it can be found below:
source 'http://rubygems.org'
gem 'rails', '3.2.8'
gem 'rubyzip', '< 1.0.0'
gem 'roo','1.12.1'
gem 'mysql2', '0.3.11'
gem 'jquery-rails', '2.1.2'
gem 'haml', '3.1.7'
gem 'thin', '1.4.1'
group :development do

end

gem 'execjs','2.0.0'
group :assets do
gem 'stylus', '0.7.1'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.3.0'
end
What should I do to get this to work? Any help would be greatly appreciated.
Updated:
I updated my question rgrd Brad suggestion accordingly.
I've performed as suggested. but when I have node.js uninstalled, I rather got another error like below "The node.js runtime is not available". any idea?
You can see the answer here
I changed from coffee-script-source 1.12.2 to 1.8.0 in Gemfile.lock file.
ex) coffee-script-source (1.8.0)
And then, in cmd, I put a command like 'bundle install'.
If you do not have a bundle, you can install bundle such as
gem install bundle
Finally, turn off your rails server and turn on again.
Thank you.
I am trying to learn Ruby on Rails through this online tutorial
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book
I'm creating an app demo_app for their second chapter.
This is what my gemfile currently looks like
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.4'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.2'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'
group :doc do
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', require: false
end
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano', group: :development
# Use debugger
# gem 'debugger', group: [:development, :test]
this is what it's supposed to look like
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.4'
group :development do
gem 'sqlite3', '1.3.8'
end
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'

group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
I don't understand why my gemfile looks so different.
I have the updated versions of rails, ruby and gemfile.
I even ran the commands
bundle install --without production
bundle update
bundle install
and my gemfile still looks like my first snippet of code.
I've been reading through chapters 1 and 2 of this tutorial but can't figure this out. Am I supposed to edit Gemfile in the text editor? I've already tried that and I got a hundred error messages.
How do I install the gemfile so it looks like the code in the second snippet?
Please help
Let's look through the gemfile item by item (Note that any of the numbers after gems are versions and it isn't necessary that your versions match his. You can specify them if you'd feel more comfortable but unless you come to some bug that needs it, you should be fine without.)
source 'https://rubygems.org' - You both have this and this is where the gem, bundle, etc. commands in the console get your gems from for installation.
ruby '2.0.0' - He has this and you don't. What is this doing? It's specifying the version of ruby that he's using in his rails app. You can do this if you want but it won't be necessary unless you've got multiple versions of ruby installed. Perhaps you're using RVM (Ruby Version Manager) in which case this will probably be necessary. Make sure it's the version you have by using ruby -v in the console to check your version. (Output will look something like this: ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0] where in the gemfile you can leave everything off besides the 2.1.1
#ruby-gemset=railstutorial_rails_4_0 - This is a comment in his gemfile for his own use. Likely he has multiple gem files and this helps him know which one to use when making the tutorial.
gem 'rails', '4.0.4' - You both have that which is just the version of rails you're using.
Next we have
group :development do
gem 'sqlite3', '1.3.8'
end
This is somewhat different than yours but how come? First of all the group :development do means that we only want to "do" (read: use) the gems in this block when we're in the development group. This one can be more clearly called an environment and can be configured/found in the config/environments/ folder. This is useful for having different gems and settings when running the rails server in development or test or production mode. He has the sqlite3 gem in the development group because he wants to use rails's default database gem for the tutorial. You will notice that you have the sqlite3 gem as well which means you can follow his tutorial successfully.
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
You have all these gems in your gemfile as well so no problems there. (They may be with different versions and with comments above them so that you know why each gem is there which is good. Rails puts the comments in by default for clarity in coding.)
group :doc do
gem 'sdoc', '0.3.20', require: false
end
Same as yours and likewise used for the docs group. It means that it won't be used unless you're specifically looking for it.
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
From person experience, I know that these are two gems that are required to deploy an app in production to heroku (a free hosting site) which you'll cover in chapter 1.4. You do not have them because you don't need them until you deploy to heroku. The production group again specifies that you want these gems for when the server runs in production (as it will on heroku). The pg gem is for postgres which is a database alternative to sqlite3 and the rails_12factor is something that enhances 12factor app handling. More can be learned here but it is only necessary to know that heroku requires it to host a rails app.
All the gems in yours that aren't in his and are commented out in yours are old rails standards that are left in because plenty of people still use them and they aren't truly phased out yet. They will not be necessary for the tutorial and you can delete them if you'd like.
Sorry it was long. Hope this helps your understanding.
It looks like your going through Hartl's tutorial, it's a great tutorial, however, if this is your first time coding and or using an MVC framework, everything is going to look like gibberish. Although this is bad practice moving forward, I suggest copying the entire gemfile that Hartl provides into your gemfile and then do a bundle install.
The point of this tutorial for beginners is to get through it with a BASIC understanding of how everything works. It's going to go over a lot of concepts that your not necessarily going to understand or use right away. The best thing to do is power through the best you can and try to finish the app. I finished it in 3 weeks and was more confused than ever, things only started to sync in once I started experimenting on my own and using the tutorial and other ruby/rails docs as a reference.
Programming is hard, and if this is your first foray into application development, I suggest having a basic understanding of Ruby first (http://www.codecademy.com/tracks/ruby) or even learning a scripting language like python (http://www.learnpython.org/). Learning python basics for some odd reason helped me understand ruby better, which made it easier to navigate and understand all the components of rails.
Anyway good luck and stick with it, there are tons of online resources to get you where you need to go. You just have to keep digging.
I'm running Windows 7 x64, Ruby on Rails 3.2.13 from RailsInstaller.
When I run my thin server and reload the Local Host I run into this:
$ thin start
>> Using rack adapter
>> ......
>> Listening on 0.0.0.0:3000, CTRL+C to stop
The system cannot find the path specified.
This is because of the error:
ExecJS::RuntimeError at /
["ok","(function() {\n\n\n}).call(this);\n"]
(in C:/Users/..../assets/javascripts/info.js.coffee)
info.js.coffee being an empty file and recent one I created from rails g controller info. In my browser with the better_errors gem, I see I have an error with the application layout on this line:
6 <%= javascript_include_tag "application" %>
I've been trying to correct this issue and did everything that was done in this question yet none of it worked. I uninstall Node.js completely but then it won't even let me run the server since it tells me I need a javascript runtime script and the default Windows one doesn't work.
Just now I tried to do gem install coffee-rails but run into this error:
gem install coffee-rails
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
The system cannot find the path specified.
ERROR: Error installing coffee-rails:
ERROR: Failed to build gem native extension.
c:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb

I think I'm on to something. Does anyone know how to install this?

My first Rails project deploy, and I've run into an issue.
The project is Rails 3.2.1, Ruby 1.9.3
Yesterday, I was given the hosting access, and they're having Rails 2.3.3, Ruby 1.8.7
If I'll decide to still deploy the app there, what changes do I need to make to it?
Specifically, I'm interested in Gemfile changes.
Here's my current gemfile:
source 'https://rubygems.org'
gem 'rails', '2.3.3'#'3.2.1'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'haml-rails'
gem 'haml'
gem 'omniauth-twitter'
What do I need to change? How do I look-up all the required dependencies and gems versions for old Rails versions?
Downgrading from 3.x to 2.3 is the dumbest thing you can do in your case.
Install gems locally, or ask your hosting company support department — they have to help.
If you can't, save your time — use Heroku, OpenShift or any other hosting company.
I'd like to now if anybody could help me with my heroku deployement.
I've set up my Rails 3.2 app with the following Gemfile
source 'https://rubygems.org'
gem 'rails', '3.2.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'mongoid'
gem 'bson_ext'
gem 'mongoid_slug'
gem 'heroku'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem "compass", ">= 0.12.alpha"
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
And I have run the rails g mongoid:config command
From the heroku support, I've added the mongolab extension and changed the mongoid.yml evironnement variables to MONGOLAB_URI
When I then deploy the app, it doesn't run on heroku.
I'm not sure what is going on, but i get this error message in the Heroku logs:
WARNING: Invalid .gemspec format in '/app/.bundle/gems/ruby/1.9.1/specifications/actionmailer-3.2.0.gemspec'
2012-01-29T19:13:46+00:00 app[web.1]: Could not find activemodel-3.2.0 in any of the sources
here is the full log file:
https://gist.github.com/1700231
has anybody experienced the same issue? I'm not sure if the problem comes from my set up or if I need to add something to rails to work with mongoid?
Cheers.
It's been a bit of pain int the b*tt, but I'm finally there.
http://railsapps.github.com/rails-heroku-tutorial.html
is the right place to go to deplay rails 3.2 on heroku.
This said my head hurt, not too much fun to get so many hurdles when one wants to learn.
Octopress looks fine at the moment I tell you :)
Alright let's keep going
