ruby-on-rails - 如何更新Ruby，Rails和Spree:请一些指针？

我正在考虑更新这个庞大的网站。它是巨大的。它使用Ruby1.9.3-p448、Rails3.2.17和Spree2.0.0我想把它推到Ruby 2.1.1、Rails 4.1-stable和Spree 2.1.0。
第一件事：
我去了gemfile，在第2行写了ruby '2.1.1'这是要做的第一件事：升级语言本身。在终端，我做了通常的bundle操作，结果出错了。发现调试器gem在2.x区域中不工作。突出显示推式删除。笑了。运行bundle。很高兴地笑了，因为很高兴看到所有的事情都在这样一个复杂的系统中工作。
然后我运行bundle exec rake db:test:prepare。
第一个错误：

rake aborted!

好啊。。。在gemfile中。。。

gem 'iconv'

在abundle exec rake db:test:prepare之后再次运行bundle：

我的问题不是怎么解决这个问题，也不是为什么它都坏了，但是你有什么建议吗？我如何找出Digest::Digest的来源？我们没有在网站上使用它，因此这是一个宝石的问题。我可能需要处理更多的“贬低”警告，所以在我花上几个小时去做之前，我只需要知道是否有人必须经历我现在正在尝试的任何事情。
非常欣赏恐怖故事。

最佳答案

我不认为文摘是你问题的原因MySQL似乎无法正确连接到数据库您确定您的config/database.yml设置适合您当前的环境吗？
我不确定，但如果错误指向directly at this line，那么我最好的猜测是您的数据库在config/database.yml中配置错误。
