当我尝试运行命令来迁移数据库时,

<server>:/usr/share/puppet-dashboard# rake RAILS_ENV=production db:migrate

我收到以下错误：

当我第一次尝试启动puppet-dashboard服务时,它抱怨它找不到rake~> 1.1.0所以我安装了.

现在我收到以下错误：

Missing these required gems:
 rack  >= 0

然而…

# gem list
*** LOCAL GEMS ***
hiera (0.3.0)
rack (1.4.1,1.1.0)
rack-test (0.6.1)

机架已明确安装.读完this question之后,我甚至删除了机架1.4.1只留下了1.1.0,但我得到了同样的错误.
