我目前正在我的 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”）。我已经对此进行了一些搜索，但没有看到与我相关的任何内容。

我正在使用 rvm-capistrano 和 ruby​​ 2.0.0-p195。我最近将我的应用程序所需的环境变量移到了 .bashrc 中。

我也有这个问题，但原因不同。我们正在使用 rvm-capistrano，我们的项目有一个 .rvmrc 文件。deploy:assets:update_asset_mtimes Capistrano 任务在服务器上运行一个 shell 命令来捕获资产清单的内容。部署中存在 .rvmrc 文件生成了来自 RVM 的“您正在使用 '.rvmrc'，它需要信任...”警告，该警告无意中成为了 shell 命令输出的一部分。我只是在使用 puts 语句对本地 capistrano gem 中的 assets.rb 配方进行检测后才看到这一点。

我通过在服务器上运行“rvm rvmrc warning ignore all.rvmrcs”解决了我的问题，然后再次部署。

另一种选择是从 .rvmrc 和整个信任的东西切换到使用 .ruby-version 方法。请参阅使用 rvmrc 或 ruby​​-version 文件使用 RVM 设置项目 gemset？详情。

这来自您的.bashrc. 检查此问题以获取更多详细信息：使用 Capistrano 部署时出现 psych.rb 错误“在此上下文中不允许映射”
