Redmine耙任务失败

Question

在SO上发布看起来像rubygems问题。我正在尝试在我的redmine安装的cronjob中运行rake任务，但它失败，找不到错误gem。下面是日志：

现在我不太清楚，为什么是i18n-0.6.11没有发现我已经在全球范围太（使用RVM）安装它。此外，正在使用的宝石显示为/var/lib/gems/1.9.1/gems，这与我的宝石目录不同。安装细节：

管理平台的安装目录：〜/管理平台
RubyGems的目录：/usr/local/rvm/gems/ruby-1.9.3-p551/gems

Answer 1

问题是我使用rvm进行ruby版本管理，但是我也安装了ruby形式的ubuntu源代码，执行rake任务的cron使用的是系统安装的ruby。所以解决方案是运行：
rvm cron setup

Answer 2

尝试在管理平台目录下执行bundle install和然后尝试再次启动redmine服务器。
