尝试将 Rails 应用程序推送到 Heroku 时加载错误

Question

我有一个 Rails 应用程序，我一直在尝试将其推送到 Heroku。但是，每当我运行 git 推送 heroku master 时，都会返回以下错误：

 To https://git.heroku.com/top5application.git
  ! [remote rejected] master -> master (pre-receive hook declined

我查看了堆栈跟踪，它表明：

 remote:        LoadError: cannot load such file -- List

由于 List 是应用程序中的模型，我检查了该文件并将其中的 require "List" 命令灰显，但这没有任何区别。

我非常感谢任何人对此有任何见解，因为我到处搜索但找不到可行的解决方案。

编辑：堆栈跟踪是：

Answer 1

从模型 List 和 User 中删除 require 'List'。

不需要在模型中加载模型，因为 app 目录中的所有文件将由 Rails 自动加载。

Answer 2

我想通了。我只是将删除 require 'List' 后所做的更改提交给 heroku 而不是 master。您必须先将更改提交到 master，然后将它们推送到 Heroku。
