Question

我第一次尝试学习Ruby on Rails，安装/设置是很多东西，我遇到了一些麻烦。特别是http://www.railstutorial.org/book/beginning#uid28 Heroku设置的1.4.2部分。

当我输入命令git push heroku master时，我收到错误，导致我无法继续学习本教程。如果我应该提供任何其他信息，请告诉我。

问题似乎是

Running: rake assets:precompile
       rake aborted!
       NoMethodError: undefined method `configure' for #<FirstApp::Application:0x007fee78f193e8>

但是在本教程中，我不记得创建/编辑任何名为configure

的方法

的Gemfile：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'
group :development do
  gem 'sqlite3', '1.3.8'

end

<强>配置

这是您的细读错误：

未定义的方法`configure'

-

问题似乎是您在configure / config/application.rb / config/environments/development.rb个文件

中有“config/environments/production.rb”的某种引用

我刚看到你的编辑，然后去教程看看是什么。我找不到configure的任何引用，所以我去找了一些答案，找到了this：

我通过以下步骤解决了这个问题。

第1步：转到app / config / initializers / development.rb

更改此行

Rails.application.configure do致

Your_Rails_Application_Folder_name::Application.configure do   示例

我的rails项目文件夹名称为'Spree_demo'   **Your_Rails_Application_Folder_name**

在以下一行

Your_Rails_Application_Folder_name::Application.configure会这样做   替换为

SpreeDemo::Application.configure请注意：请参阅下划线   应用程序文件夹名称被删除。

希望它适合你们。
