这是一个非常基本的红宝石宝石问题.我很熟悉编写这样的简单ruby脚本:
#!/usr/bin/ruby
require 'time'
t = Time.at(123)
puts t
现在我想在我的脚本中使用我自己的ruby gem.在我的rails项目中我可以简单地说require 'my_gem'.但是,这在独立脚本中不起作用.在独立的ruby脚本中使用我自己的gem的最佳/正确方法是什么？
我正在尝试在我的Mac上安装Bundler gem.使用命令:
sudo gem install bundler我收到以下错误:
ERROR: Could not find a valid gem 'bundler' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.8.gz)
它显然似乎是一个服务器问题,但我该如何解决这个问题呢？gem update --system目前是最新的.有没有另一种方法来获得Bundler？
我有一个小型的网络应用程序,它使用了一堆宝石.其中一些仅用于test和development环境.现在,当我尝试使用以下命令在生产服务器上启动unicorn时,它会失败.
unicorn_rails -E production -D -c config/unicorn.rb
我在日志文件中看到的错误是:
Refreshing Gem list
Could not find gem 'spork (>= 0.9.0.rc2, runtime)' in any of the gem sources listed in your Gemfile.
Try running `bundle install`.
我在下面粘贴了我的gemfile:
source 'http://rubygems.org'
gem 'rails', '3.0.1'
gem 'unicorn'
gem 'mongoid', '>= 2.0.0.beta.19'
gem 'devise'
gem 'cancan'
gem 'haml', '>= 3.0.0'
gem 'bson'
gem 'bson_ext'
gem 'formtastic'
gem 'bluecloth'
group :production do
gem 'capistrano'
end
group :development do
gem 'haml-rails'
gem 'hpricot', '0.8.2'
gem …我刚刚编译了ruby并安装了rubygems,mysql2和rails,它们工作得很好.但每当我尝试启动rails服务器时,我都会收到以下错误消息:
/usr/local/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6/lib/mysql2.rb:7:in `require': dlopen(/usr/local/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError) Referenced from: /usr/local/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle Reason: image not found - /usr/local/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6/lib/mysql2.rb:7:in `' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:68:in `require' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:68:in `block (2 levels) in require' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:66:in `each' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:66:in `block in require' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:55:in `each' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler/runtime.rb:55:in `require' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.10/lib/bundler.rb:120:in `require' from /Users/filzo/Documents/rails/blog/config/application.rb:7:in `' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/railties-3.0.5/lib/rails/commands.rb:28:in `require' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/railties-3.0.5/lib/rails/commands.rb:28:in `block in ' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/railties-3.0.5/lib/rails/commands.rb:27:in `tap' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/railties-3.0.5/lib/rails/commands.rb:27:in `' from script/rails:6:in `require' from script/rails:6:in `'
我尝试了几种可能的解决方案(例如:http: //railsforum.com/viewtopic.php？pid = 23125#23125 with libmysqlclient.18.dylib); 但没有什么对我有用.我希望你能帮助我. …

我刚刚成功安装了bundler-1.3.3.但是,当我尝试运行bundle install时,我得到了

这有什么不对？
