Question

我一直在尝试将我的应用程序从Rails 2.3升级到Rails 3.我让rails无故障，但没有任何错误，因为我没有迁移数据库。我已经解决了许多错误，试图运行rake db：migrate但是我无法通过这个......

rake aborted!
no such file to load -- config/environment

(See full trace by running task with --trace)

我的配置环境是

#Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
AppName::Application.initialize!

带痕迹

    no such file to load -- config/environment

有什么想法吗？

我不确定您是否看过这个，但有一个rails插件提供rake任务来帮助进行此升级：https://github.com/rails/rails_upgrade

它给你：

rake rails:upgrade:check
rake rails:upgrade:configuration

但我认为您最终需要做的是生成一个新的空rails 3应用程序并将生成的config/environment文件复制到您的应用程序中。

rake db：migrate期间的错误
