Ruby on Rails控制台 - 未定义的方法 `assets`

ruby-on-rails

在这个项目中，控制台无法启动，我尝试了谷歌上能找到的所有方法。我运行了"rails c"命令，但是收到了一个错误提示：
/Users/gorbunov/.rvm/gems/ruby-2.4.1/gems/railties-5.2.0/lib/rails/railtie/configuration.rb:97:in `method_missing': undefined method `assets' for #<Rails::Application::Configuration:0x007fae6a9bdf78>

我不知道该怎么办。非常感谢！

你的 config/application.rb 中未定义 assets 方法，请尝试将其删除。 - rails_id
请检查此行代码 from /Users/gorbunov/Projects/buktopuha_api/config/environment.rb:5:in <main>'`。 - Akash Pinnaka
你可以参考以下线程，这可能会对你有所帮助 https://github.com/fgrehm/letter_opener_web/issues/46 - Gokul P
@rails_id 在config/application.rb中没有assets方法。 - Pum Purum
Rails.application.initialize! → Rails应用程序初始化！ - Pum Purum

你是否已经安装了sass-rails、jquery-rails和uglifier？同时在application.rb文件中添加一行代码require "sprockets/railtie"，然后检查它是否正常工作。 - Akash Pinnaka

我曾遇到此问题，找到了这里的解决方案，即需确保config/application.rb中有sprockets行。

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，以上行在不同版本的rails之间略有不同。您可以在您所使用的rails版本的rails指南中找到它应该看起来像什么。这里是Rails 6.1，这里是7.0。
有趣的是，我刚刚删除了require "sprockets/railtie"，因为我试图移除sprockets。无论如何，我把它放回去了，现在Rails又很开心了。

补充一下，你还需要在你的gemfile中添加这个

gem 'sprockets-rails'
