Activerecord Gentoo上的Redmine：未定义的方法'active#u record'；对于#<；Rails:：Application:：Configuration:0x00000000ea5538>；（命名者）

在Gentoo上运行Redmine简直是人间地狱（至少对我来说，因为我对ruby知之甚少）！我目前正在通过passenger和apache“运行”Redmine 2.3.2，因为有些日子我得到的只是

undefined method `active_record' for #<Rails::Application::Configuration:0x00000000ea5538> (NoMethodError)

天哪，我自己解决的

Gentoo拉入的依赖项似乎无效

我从中手动下载了这个文件

http://www.redmine.org/projects/redmine/repository/entry/tags/2.3.2/Gemfile 

然后跑

bundle install --without development test

一切都安装好之后

emerge --config "=www-apps/redmine-2.3.2

在我重新启动apache之后，它完美地运行并出现了Redmine

我希望这篇文章也能帮助其他Gentoo用户。

也有同样的问题，在遵循您的答案后，仍然得到了答案 “无法加载这样的文件--/var/lib/redmine/config/environment”错误

通过执行“chown-rache:apache/var/lib/redmine”解决了这个问题

相应地，一些更新将文件的所有权更改为“redmine”用户

---

它现在对我有效。

也有同样的问题，丢失了活动记录。非常感谢，你的解决方案。。。（仍在进行中）。感觉怪怪的，因为我不知道自己在做什么。我还必须安装ImageMagick manuall，因为gem rmagick的一些本机扩展无法构建。在我看来，红色的ebuild需要修复。但我不知道怎么。。。

bundle install --without development test

emerge --config "=www-apps/redmine-2.3.2
