我正在设置一个带有 RVM 和 CAPSTRANO 的新服务器。

但是当我部署服务器时，我得到了一个错误：

  * 2013-06-13 16:39:50 executing `deploy:assets:update_asset_mtimes'

/home/rails/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/psych.rb:203:in `parse': (<unknown>): control characters are not allowed at line 1 column 1 (Psych::SyntaxError)

我从中找到了答案： psych.rb error when deploying with Capistrano 'mapping not allowed in this context'

但是当我使用 cap 时，如何禁用输出“将包装器保存到.......”？也适用于 bash shell "rvm use ***" ?

谢谢！

【解决方案1】：

当我遵循 mpapis 关于https://github.com/wayneeseguin/rvm/issues/1964#issuecomment-19437861 的建议时，我发现 rvm 停止打印“将包装器保存到.......”，即从 rvm 安装上的 after_user_textmate 挂钩中删除执行权限。

对于我的系统，我跑了（代替你自己的rvm安装目录）：

chmod a-x /usr/local/rvm/hooks/after_use_textmate
