我正在考虑更新这个庞大的网站。它超大。它使用 Ruby 1.9.3-p448、Rails 3.2.17 和 Spree 2.0.0。我很乐意将它推送到 Ruby 2.1.1、Rails 4.1-stable 和 Spree 2.1.0。
要事第一:
我去了 gemfile 并在第 2 行写了 ruby '2.1.1'。这是要做的第一件事:升级语言本身。在终端中，我做了通常的 bundle 并得到了一个错误。发现调试器 gem 在 2.x 领域不工作。突出显示它。推送删除。咯咯地笑。运行 bundle。高兴地笑了，因为看到一切都在如此复杂的系统中工作真是太好了。
然后我运行了bundle exec rake db:test:prepare...
第一个错误:
rake aborted!

我的问题实际上不是我该如何解决这个问题或为什么它会崩溃，但你有任何指示吗？我如何找出 Digest::Digest 来自哪里？我们没有在站点中使用它，因此它是一个 gem 问题。我可能不得不处理更多的“弃用”警告，所以在我花上几个小时之前，我只需要知道是否有其他人必须经历我现在正在尝试的任何事情.
非常感谢恐怖故事。
最佳答案
我不认为 Digest 是您问题的根源。看来 MySQL 无法正确连接到您的数据库。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在 config/database.yml 中错误配置了数据库。
