问题 I need a two sided multi select box in Rails (3.2.8), just like here: http://www.stevefenton.co.uk/Content/Jquery-Two-Sided-Multi-Selector/ However, I can't get this to work with Rails and it is so poorly documented I have to give up on that one.

Many thanks! 回答1: You could try this one: http://quasipartikel.at/multiselect/ Or this is another: http:

问题 This question already has answers here : Can I delete some folders of nokogiri and capybara-webkit inside of my rvm gemset? (2 answers) Closed 5 years ago . I have to use nokogiri for some xml processing. For this I create a rvm gemset specific to the project and install nokogiri by gem install nokogiri. No problems this far.

问题 Using RoR 4.1.4 I am trying to use the leaflet-rails gem. I followed the steps outlined in the github page, but when I try to load the map, I see ReferenceError: L is not defined in the browser console.

However, the head section of the page shows that /assets/leaflet.js is being referenced and it actually IS there. When I look at the generated code: <div id="map"></div>

问题 I'm running on nitrous.io and trying to install the rgeo gem using ruby 2.0.0-p353. I don't have sudo access, so I tried to compile and install geos from source. Once I downloaded and untarred the source files, I cd into the source folder and run mkdir /home/action/local && ./configure --prefix=/home/action/local make && make install This runs for a bit. I then run gem install rgeo -- --with-geos-dir=/home/action/local Things look alright, but if I hop into a terminal I get RGeo::Geos

问题 I'd like to be able to use both the google-api-client gem to do service to service authentication and the google_drive api to access spreadsheets. Unfortunately, these gems seem to conflict due to requiring different versions of Faraday in their dependencies. Anyone know how to solve this? Error if google_drive is required first: specification.rb:1637:in `raise_if_conflicts': Unable to activate google-api-client-0.4.4, because faraday-0.8.1 conflicts with faraday (~> 0.7.0) (Gem::LoadError)
