尝试使用capistrano进行部署时，为什么会出现Psych错误？ [英] Why am I getting a Psych error when trying to deploy with capistrano?

问题描述

我目前正在Rails 3.2.13应用程序中设置capistrano。我收到以下错误/详细信息（包括第1行第1列不允许使用控制字符）。我已经做了一些搜索，但是没有看到任何与我相关的东西。

I am currently setting up capistrano in my Rails 3.2.13 app. I am getting the below error/details (including "control characters are not allowed at line 1 column 1"). I have done some searching for this but do not see anything related to me.

我正在使用rvm-capistrano和ruby 2.0.0-p195。我最近将应用所需的环境变量移到了.bashrc中。

I am using rvm-capistrano and ruby 2.0.0-p195. I recently moved my app-required environment variables into .bashrc.

推荐答案

这来自您的 .bashrc 中的一个可能的问题。
检查此问题以获取更多详细信息： psych.rb错误在此情况下不允许映射

This comes from a possible problem in your .bashrc. Check this question for additional details: psych.rb error when deploying with Capistrano 'mapping not allowed in this context'
