Question

我正在努力解决Sinatra中的麻烦。我将ruby更新到2.0.0并完成了我的应用程序的迁移，这些应用程序完全在1.8.3上运行。

捆绑安装完成但我运行时

bundle exec rackup

我有以下错误。如果您有任何解决方案，我将不胜感激。

我正在使用MacOS X 10.10.2，ruby2.0.0

捆绑exec rackup 法拉第:: Builder现在是Faraday :: RackBuilder。 /Users/user/Documents/fishingderby/vendor/bundle/ruby/2.0.0/gems/activerecord-4.1.13/lib/active_record/connection_adapters/connection_specification.rb:190:in rescue in spec': Specified 'mysql2' for database adapter, but the gem is not loaded.

Answer 1

我发现这很有效。

在Gemfile中，指定如下。

gem'mysql2'，'〜＆gt; 0.3.20'

实际安装了mysql2（0.3.20）。

最新mysql2上的任何错误？

没有加载gem mysql2 gem
