ruby-on-rails - 使用 capstrano 部署时如何禁用 rvm 输出？

Question

我正在使用 RVM、CAPSTRANO 设置新服务器。

但是当我部署服务器时，出现错误:

  * 2013-06-13 16:39:50 executing `deploy:assets:update_asset_mtimes'
  * executing "[ -e /home/rails/server/blog/shared/assets/manifest.yml ] && cat /home/rails/server/blog/shared/assets/manifest.yml || echo"

/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!

Answer 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 Hook 中删除执行权限。

对于我的系统，我运行了(替换您自己的rvm安装目录):

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