问题 I'm trying to install geoutm using gem install geoutm . The Github repository doesn't have an issues page, so I'm trying to fix the issue myself then submit a pull request.

(TypeError) no implicit conversion of Array into String It says "successfully installed", but trying to require the gem fails. Verbose install isn't much more useful: $ gem install

问题 I was just about to install a Ruby gem by someone I hadn't heard of. But something made me think "Who is this guy?". Is there any risk of a Ruby gem accessing private data on your machine and transmitting it elsewhere - since the gem system has Internet access? Or are there protections against this? 回答1: Of course there is. You're installing software on your computer that runs with the privileges of the script/user that calls it. It's probably easier to spot malicious code in pure Ruby than

问题 I'm new in ruby on rails, and I am trying to create a tutorial. I have a problem when I execute rake db:migrate . hugo@ubuntu:~/pin_board$ rake db:migrate /home/hugo/.rvm/gems/ruby-2.2.2/gems/activesupport-4.0.5/lib/active_support/values/time_zone.rb:283: warning: circular argument reference - now What causes this? Can somebody help me? 回答1: You see this warning message because your Rails version is 4.0.5. The issue has been fixed on Rails 4.0.6. Update your Gemfile and run bundle update

问题 I'm creating a new plugin for a jruby on rails application that will eventually be turned into a gem. Inside my plugin I have controllers, helpers and views. For my views I'd like to use Haml. The problem is that I can't seem to get it to recognize that they are haml templates. Is it even possible to do this? Is there a way for a plugin to have Haml as a dependency for its view? And by that I mean, I intend for the plugin that I'm creating to have a view created by the plugin, that can be

问题 I've just pulled down Octopress from Git ( github.com/imathis/octopress.git octopress ) to my local machine, but when I try to run bundle install per the instructions, ( http://octopress.org/docs/setup/ ) I get a make error. I'm running version 3.2 of Xcode--do I need to update to 4.x from the Apple Developer site? I'm also running Ruby 1.9.2p180 per RVM. Do I need to run a more recent version? Here's the output when I try to run sudo gem install RedCloth: Building native extensions. This

问题 When I compile my SCSS, I'm getting a "file not found" error that leads me to believe there is something wrong with my config.rb. The error from the command line includes part of the path twice as well as the ".." relative directory: File not found or cannot be read: C:/REALLY_LONG_PATH/C:/REALLY_LONG_PATH/../img/avatar.jpg The config.rb reads as follows: # Delineate the directory for our SASS/SCSS files (this directory) sass_path = File.dirname(__FILE__) # Delineate the CSS directory (under

问题 i want to copy all of my gems from one machine (foo) to another (bar). both machines are identical except that foo has a bunch of gems installed and bar does not (bar cannot get onto the internet). i copied /usr/local/lib/ruby/gems from foo to bar, and now bar recognizes that the gems are installed. root@bar # gem list *** LOCAL GEMS *** keybox (1.2.1) rake (0.9.2.2) ... and so on if i try to run them from their native location, they work as expected root@bar # cd /usr/local/lib/ruby/gems/1.8

问题 How to specify gem dependencies in a way that user with only ruby, rake and rubygems installed could issue a single rake command to install all the dependencies required? Is it possible to use the same dependency specification when building gem with GemBuildTask? 回答1: It's actually pretty easy to set up a rake task that installs a bunch of gems: task :install_gems do require "rubygems" require "rubygems/dependency_installer" installer = Gem::DependencyInstaller.new [["rack"], ["merb-core", "1

问题 Using Rails, whenever I try to do anything like "bundle install" or sudo gem install someGem, I get these same errors about sqlite3.

问题 So I'm writing what I thought was a simple .rb file to convert a float number into a string. The string returns my floating point number in words. So if I have 11.11 then I would have eleven dollars and eleven cents So far I've extended the float class which has worked alright.
