针对任何示例应用程序使用RailsApps composer工具的安装问题

Question

我使用的是Ruby2.2.2& Rails 4.2.1，在带有node.js的Ubuntu14.04上运行RVM。

对于我试图创建的任何示例应用程序，我在composer过程中都会遇到反复出现的错误。我怀疑问题出在解析yaml文件-- secrets.yml，但我没有看到任何异常(与其他rails应用程序相比)。我已经尝试了不同的应用服务器，并在devlopment.rb中明确命名秘密，但没有成功。如果下一步能找到方向我会很感激。

这个问题与.bashrc中预先存在的环境变量有关，尽管我不清楚问题是什么。我注释掉了这些行，这使得composer能够正确地安装应用程序。这些变量的格式似乎是正确的，并且在过去没有引起过问题。很明显，解析Rails.appplication.secrets时出现了问题。我怀疑当您有现有的ENV并在开发中使用secrets.yml时，可能会发生冲突。
