Question

您好我正在将Rails 2应用升级到Rails 3。当我想运行类似：rails c，rake -T等的内容时，会抛出这样的内容：

$ rails c
/usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/railtie/configuration.rb:77:in `method_missing': undefined method `assets' for #<Rails::Application::Configuration:0xb6569120> (NoMethodError)
    from /home/neoriddle/proyectos/interkids/config/application.rb:49
    from /usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/commands.rb:21:in `require'
    from /usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/commands.rb:21
    from script/rails:6:in `require'
    from script/rails:6

这是rails c，下一个日志正在运行rake -T：

$ rake -T --trace
rake aborted!
undefined method `assets' for #<Rails::Application::Configuration:0xb658aa64>
/usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/railtie/configuration.rb:77:in `method_missing'

你有什么想法可以解决这个问题吗？

Answer 1

资产管道直到rails 3.1才被包括在内。将rails gem（和app）升级到rails 3.1 +。

Answer 2

我遇到了同样的问题，但在下面解决了。

Ruby -v: 3.0.2 Rails -v: 6.1.3

config/application.rb

require "sprockets/railtie”

终端

$ mkdir -p app/assets/config && echo '{}' > app/assets/config/manifest.js

Answer 3

我的应用是api_only，因此Rails在生成新资源时跳过了创建资产的操作。

我从config.assets和development.rb中删除了对production.rb的引用，并且有效。

从本质上讲，如果您的应用不需要assets，则可以将其删除。

#lort :: application :: configuration> </rails :: application :: configuration>的未定义方法`assets'
