Аргумент require_tree должен быть каталогом в обновленном приложении Rails 5

Я только что обновил свое приложение с Rails 4.2.7 до Rails 5.0.0.1. Я использовал RailsDiff, чтобы убедиться, что все покрыто, и я полагаю, что сделал. Пока все работает до загрузки моего приложения.

Теперь я вижу эту ошибку:

Sprockets::ArgumentError at /
require_tree argument must be a directory

Это мое application.css:

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or any plugin vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any other CSS/SCSS
 * files in this directory. Styles in this file should be added after the last require_* statement.
 * It is generally better to create a new file per style scope. *
 *= require_tree .
 *= require_self
 */

Это мое application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

Это выглядит так:

Sprockets::ArgumentError - require_tree argument must be a directory:
  sprockets (3.7.0) lib/sprockets/directive_processor.rb:182:in 'rescue in block in process_directives'
  sprockets (3.7.0) lib/sprockets/directive_processor.rb:179:in 'block in process_directives'
  sprockets (3.7.0) lib/sprockets/directive_processor.rb:178:in 'process_directives'

Я не использую никаких плагинов. Это довольно простое/ванильное приложение. Единственный стиль - по умолчанию scaffold.scss.

Что может быть причиной этого?
