Question

我正在使用Devise学习Rails并遵循本教程：https://www.sitepoint.com/devise-authentication-in-depth/

在此期间我使用Bootstrap-Sass进行样式设置。我有一个奇怪的问题，在应用程序位于Heroku上的生产中加载样式，但在我的计算机上开发时，我只是得到了空白，没有样式的形式。我觉得好像我改变了（或没有改变）某些东西的设置或版本，但我不确定是什么。我不确定为什么某些东西在Heroku上可以正常工作但在我自己的电脑上却是平稳的。

我正在使用Rails 5.下面是我的Gemfile的副本，这有帮助。我会根据需要提供其他文件/信息。

我设法用这个解决了我自己的问题（它进入了我不断增长的一堆愚蠢的错误）。而不是按照指示将我的application.css文件重命名为.scss，在我的无限智慧中，我创建了一个新的.scss文件并保留了我的旧.css文件。删除它让Bootstrap样式自由运行。我不确定Heroku为什么没有那些文件存在问题，我想它只是足够聪明才能理解我的愚蠢错误。

我应该在某些时候使用新的Bootstrap 4，但是现在我喜欢我在使用的教程中找到的样式。请继续关注更多幽默错误。
