gemfile

I have been looking everywhere to figure out this problem. I already downgraded the jquery-rails gem to 2.3.0 in my gemfile. But when I include jquery-ui in application.js I still get the Sprokets::FileNotFound error. couldn't find file 'jquery-ui' (in /home/richard/projects/pickaxe/mini-projects/depot-app/app/assets/javascripts/application.js:14) This is my application.js file: // This is a manifest file that'll be compiled into application.js, which will include all the files // listed below. // // Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets

My question is pretty much in the title. e.g. in the default Gemfile created with a Rails 3.1 app; gem 'sass-rails', '~> 3.1.5' It seems like I should know this already but I can't find any reference to it on the Bundler website. Tim Brandes From the bundler website: The specifier ~> has a special meaning, best shown by example: '~> 2.0.3' is identical to '>= 2.0.3 ' and '< 2.1.' '~> 2.1' is identical to '>= 2.1' and '< 3.0' . '~> 2.2.beta' will match prerelease versions like '2.2.beta.12' .

I keep running into the following error with my Gemfile.lock whenever I want to do a git pull or checkout a new branch. error: Your local changes to the following files would be overwritten by merge: Gemfile.lock Please, commit your changes or stash them before you can merge. Aborting The problem is that I can't figure out how to fix it. Stashing the file doesn't work -- the local changes just stay there for some reason. I've also tried running git checkout -- Gemfile.lock to discard the changes, but that doesn't work either -- the local changes just stay there. I've also tried creating a new

How to find unused gems in my Gemfile, so that I can cleanup references which are no longer used. I doubt if there is an automated way to find unused gems in the Gemfile. For someone who has built the application over time, it should be easy to manually identify gems that were discarded along the way for some reason or the other. For a legacy application inherited from someone else, it is a much difficult task to manually identify unused gems. If there is comprehensive test coverage for the system, it would help in removing unused gems by trial and error, while ensuring that the tests pass at

In my Gemfile I specified ruby version 2.0.0: ruby '2.0.0' But my console tells me I have 2.1.0dev: $ ruby -v ruby 2.1.0dev (2013-09-16 trunk 42951) [x86_64-darwin12.4.0] I am using rbenv and it tells my I don't have 2.1.0 installed, $ rbenv versions system * 2.0.0-dev Bundle update or bundle install says: "Your Ruby version is 2.1.0, but your Gemfile specified 2.0.0" but using 'rbenv local 2.0.0-dev' leaves me with ruby 2.1.0dev again. Furthermore: $ rbenv global 2.0.0-dev $ cat ~/.bash_profile: export PATH="$HOME/.rbenv/bin:$PATH" if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
