在项目中，控制台停止启动，我尝试了在Google中找到的所有内容。
我运行rails c并收到错误：

我不知道该怎么办。非常感谢！
我遇到了这个问题并在这里找到了解决方案，这是为了确保您在 config/application.rb 中有链轮线
require "rails"
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie" # <--- make sure this line is here
require "rails/test_unit/railtie"
请注意，上述行在 rails 版本之间略有不同。在版本的 rails 指南中查找您的 rails 版本应该是什么样子。这是rails 6.1，这里是7.0。
有趣的是，我刚刚卸下了require "sprockets/railtie"，因为我试图移除链轮。无论如何，我把它放回去，铁轨又开心了。
要添加到此答案中，您还需要在 gemfile 中使用它
gem 'sprockets-rails'
