在Ubuntu上启动Rails应用程序时（通过任何过程，例如控制台，服务器，Rake任务等），我从gems中得到了一个未初始化的常量错误。但是，我可以将完全相同的存储库克隆到OSX上，并且可以正常工作。我显示的错误来自于公寓，但是如果我删除对Core :: Organisation的引用，则该问题只会传播到下一个加载的gem。因此，我认为这与在应用程序中的常量之前加载宝石有关。
我尝试使用
config.eager_load = true
config.enable_dependency_loading = true
但是它没有任何改变。
更新： 我发现仅用“ Organisation”代替“ Core :: Organisation”就可以了。因此，这与命名空间有关。在基本目录中，有一个模块core.rb：
module Core
def self.table_name_prefix
'core_'
end
end
环境：

我找到了答案！
事实证明，Linux在目录方面比OSX更加混乱。我的命名空间模块位于名为“ Core /”的目录中。当我将其更改为“ core”（全部小写）时，一切都按预期工作。
