请帮助我，我已经完成了 Rails 教程的 11 章，将我的应用程序部署到 heroku（在本地运行良好）并且它一直崩溃。我正在使用 rails 5.2.2 在执行命令 $heroku run rails console 后，我收到了这个：

我知道这可以通过遵循建议的建议来解决:

我的问题是为什么行为不一致？
运行pod install时安装时遇到问题yoga。好像是我的ruby环境有问题？

我有点难住了。我的本地 rails 应用程序与 webpacker 4.2 配合得很好并做出反应，但是在部署到生产环境时can't find application in /app/public/packs/manifest.json出现了奇妙的错误。
这是我尝试过的：
4.2我是否错过了构建步骤或生产中会导致这种情况的东西？还需要检查什么？

我运行以下命令以nginx交互模式启动容器：
docker run -i -t nginx:latest /bin/bash
现在我正在尝试安装nano编辑器，以便使用以下命令查看nginx配置 ( nginx.conf)的配置：
apt-get update
apt-get install nano

但是，当我运行第一个命令时apt-get update，出现以下错误：

我有一个看起来像这样的文件
#app/services/account/authenticate/base.rb
module Account
module Authenticate
AuthenticateError = Class.new(StandardError)
class Base < ::Account::Base
def self.call(*attrs)
raise NotImplementedError
end
end
end
end
现在当我运行代码时rails c出现错误
> ::Account::Authenticate::AuthenticateError
=> NameError (uninitialized constant Account::Authenticate::AuthenticateError)
> ::Account::Authenticate.constants
=> [:Base, :ViaToken]
所以 rails 没有看到 AuthenticateError 类。但是当我从这个文件夹创建一个嵌套类时
=> Account::Authenticate::ViaToken
> ::Account::Authenticate.constants
=> [:Base, :AuthenticateError, :ViaToken]
AuthenticateError 类现在可见
> ::Account::Authenticate::AuthenticateError
=> Account::Authenticate::AuthenticateError
这个问题的解决方案是创建一个单独的文件authenticate_error.rb，它从一开始就可以工作，但这个解决方案对我来说并不理想。是否有任何解决方案可以预加载所有类或 smth？
