Question

我有一个Rails应用程序我一直在努力推向Heroku。但是，每当我运行git push heroku master时，我都会收到以下错误：

 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”命令显示为灰色，但这没有任何区别。

我真的很感激任何人对此有任何见解，因为我到处搜索，找不到可行的解决方案。

编辑：堆栈跟踪是：

Answer 1

从模型require 'List'和List中删除User。

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

Answer 2

我明白了。我只是在删除了需要'List'到heroku而不是master之后做出的更改。您必须先将更改提交到master，然后将它们推送到Heroku。

尝试将Rails应用程序推送到Heroku时加载错误
