问题 I use Thin to serve the rails application located on a test machine. I'd like to be able to stop/start thin from my local machine but the following does not work: ssh luc@test_machine '/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin -v' I got the following error message: /home/luc/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find thin (>= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4]

问题 I have a rails 4 project that has been working for some time. I attempted to install taps but got an error message: $ gem install taps /usr/local/rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/psych.rb:370:in `parse': (<unknown>): mapping values are not allowed in this context at line 2 column 29 (Psych::SyntaxError) from /usr/local/rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/psych.rb:370:in `parse_stream' from /usr/local/rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/psych.rb:318:in `parse' from /usr/local/rvm/rubies

问题 On running bundle install, coming up with the following error. So it's not an issue of finding the config file - it knows where it is...just not executing it. I do have xcode installed. I've checked on multiple questions and a lot of it is pointing me to being explicit on where the config file is, but that's not my issue per se. Any ideas? Installing mysql2 0.3.21 with native extensions Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: /private/var/folders

问题 Had some trouble with bundler trying to install the 'nokogiri' gem, so we went ahead and installed it manually with 'gem install nokogiri' - this was within an RVM ruby, and installed with native extensions. Now, when running 'bundle install', it appears that bundle still tries to install nokogiri! I've seen it said that when bundle runs, it checks locally for gems first, why might this not be happening? UPDATE: We are using Capistrano to deploy, and when i override the 'bundle:install' task

问题 I get this error when I run a new empty rails (4.0) site: Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 'sqlite3'` to your Gemfile. I have a valid sqlite3 gem built with the devkit. I made a dumb test for that: w:...> ruby hello.rb hello world test.db is done. Which also creates an empty database, called "test.db" as shown below. Simple ruby script: require "sqlite3" puts "hello world" # Open a database db = SQLite3::Database.new "test.db" puts "test.db is done

问题 I just setup an Ubuntu 13.04 server, and installed RVM 1.21.11, Ruby 1.9.3-p448, and Rubygems 2.0.5 . Many gems, such as mongo , awesome_print , aws-s3 , and json , installed successfully. However, gems that compile an extension fail. I've tried to install nokogiri , mongo_ext , and bson_ext . They all fail in the same way, as shown below. Any idea how to fix this? [nick@mongo01 ~] gem install mongo_ext -u -V --backtrace HEAD http://rubygems.org/latest_specs.4.8.gz 302 Moved Temporarily HEAD

问题 I'm on Mac OS X 10.6 Snow Leopard. I just updated my Ruby stuff using: sudo gem update Unfortunately, it broke everything.

问题 I have a micropost form which allows a user to upload a photo and type some content to go with it. The image file field is the nested attribute from my photo model. It has a validation rule "presence => true". This is not required for microposts. User are allowed to post microposts without images/photos. How ever I use the same photo model for the users image gallery and a photo is required at the time of form submission so I can't disable this rule. Is there any way to bypass the validation

问题 The bottom line is, rbenv isn't making shims. I've exhausted ideas of what could be the problem. After a few days of banging my head against a wall to fix but no avail, I think it's time to ask for help. I'm attempting to make the switch from RVM to rbenv, so that could obviously be a factor here. Any ideas/help would be great. Here's what happens: [09:38] ~ $ gem install pry Fetching: pry-0.10.2.gem (100%) Successfully installed pry-0.10.2 1 gem installed [09:39] ~ $ rbenv rehash [09:40] ~ $
