rubygems

问题 I'm trying to access my first ruby project. After navigating to the proper directory and typing: $ rails server I get the following error message: /Users/Rozey/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.6/lib/mysql2.rb:7:in require': dlopen(/Users/Rozey/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError) Referenced from: /Users/Rozey/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle Reason: image

问题 I'm trying to setup a Unicorn on an AWS box, but the workers just keep timing out and I don't know why. I'm using a Ubuntu Server 14.04 LTS AMI, installing everything needed for a standard Ruby on Rails installation. Using rails new, I generate an empty app and attempting to access it the first time seems to be fast, but after that the workers just timeout continuously and takes forever to serve the webpage. Loading a standard WEBrick server does not have this problem and loads pages almost

问题 I'm using DevKit and XAMPP, and now I have to execute the following command: gem install mysql2 -v 0.2.6 --platform=ruby -- --with-mysql-dir="x:\Prog ram Files\mysql-5.5.11-winx64" --with-mysql-lib="x:\Program Files\mysql-5.5.11-winx64\lib" --with-my sql-include="x:\Program Files\mysql-5.5.11-winx64\include" --without-opt-dir However, XAMPP does not include a lib or include folder on its MySQL directory. What should I specify instead ? Thanks 回答1: Here's the solution I used to get Ruby with

问题 I am trying to install ruby gems on my MacOS OS X 10.5.1 behind a corporate firewall proxy. But I am getting an error about connection refused . How can I install Ruby gems on a Mac behind a corporate proxy? 回答1: Specify the proxy to use: export HTTP_PROXY='http://username:password@proxyserver.net:port/' If it's a Windows proxy (common in EnterpriseLand), it will use a custom NTLM authentication, which normal Unix apps don't do. To fix it, get NTLMAPS - a small Python app that acts as a local

问题 Note: I asked this question when I got unexpected messages when doing bundle install with the factory_girl gem using Ubuntu 11.10. Being a noob I had ... and still have ... no idea what was going on. The update below attempts to outline what I did to eventually get rid of the messages. I am leaving the question around with a slightly more pertinent title line in case it might be of use to someone else. I look at Factory Girl's README.md and I see: Install gem install factory_girl or add the

问题 When I create a Rails app I am getting some errors and I have no idea what they mean or how to fix them. Instead of explaining I am going to output what is happening, I think this might be the best approach to getting help with this: j3@j3:~/code/rails_projects$ rails new first_app create create README.rdoc create Rakefile create config.ru create .gitignore create Gemfile create app create app/assets/images/rails.png create app/assets/javascripts/application.js create app/assets/stylesheets

问题 I've setup Rails environment two days ago and I thought things were going fine but then when I ran rake test command it got aborted due to this load error: Bundler::GemRequireError: There was an error while trying to load the gem 'chromedriver-helper'` `Caused by: Selenium::WebDriver::Error::WebDriverError: not executable: "C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/chromedriver-helper-2.1.0/bin/chromedriver-helper" I tried a few things but nothing worked. I reinstalled the gem and updated it.

问题 I'm running Ubuntu 10.04 and originally installed ruby 1.9.1 (from source). I've just decided to try out ruby 1.9.2 and rails 3, and it seemed like a good time to use rvm to deal with the multiple ruby installs and gemsets. rvm installed and seems to be working, I installed ruby 1.9.2 in rvm and made that my default ruby. However, every time I try to install a gem under ruby 1.9.2 I see this error. mark@Steve-Austins-Penguin:~$ gem install haml ERROR: While executing gem ... (Errno::EACCES)

问题 I've followed the instructions here, installing the composite_primary_keys gem via sudo gem install composite_primary_keys That worked fine. Now when I add the following to my model set_primary_keys :user_id, :group_id and I get undefined method `set_primary_keys' for #<Class:0x1043bfe20> Also, using multiple primary keys in a migration as described here has no effect. Any ideas why this might not be working and how to make it work? Note: I do not want a speech on why I should not be using
