Ruby on rails cap生产部署：迁移不起作用

有没有办法解决这个问题？当我使用

cap production deploy:migrations

进行部署时，一切正常，但我的rvm出现了问题，我想，我重新安装了它，但我仍然有问题

我附上了Ubuntu终端的进度，从一切正常到出错的地方以及最后的错误消息。谢谢你的帮助

类似问题已重复出现一段时间，请检查：

这将告诉bundler使用

GEM_HOME

而不是

/var/www/apps/myapp/shared/bundle/

来安装和加载GEM

我在我的deploy/production.rb中添加了set:bundle_dir、'set:bundle_flags、--system--quiet'。这就是你的意思吗？所以我的production.rb现在看起来像：require'rvm/capistrano'server'1.2.3'，：app，：web，：db，：bg，：primary=>true-set:rvm\u-type，：user-set:rvm\u-ruby\u-string，'ree-1.8.7-2012.02'set:bundle\u-dir'，set:bundle\u-flags'，system--quiet'user'xxx'set:user'set:password，“xxx”set:use\u-sudo，false-set:use\u-set:ssh-options，{forward agent=>true}set:branch，“production”set:rails_env，“production”set:deploy_to，“/var/www/apps/myapp/”set:keep_releases，5
