我使用Ubuntu 12.04 LTS（32位，服务器），木偶2.7.17，ruby1.8.7.352 rubygems 1.8.15。 和Apache 2.2.22。
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 我得到以下错误：

当我第一次尝试启动木偶仪表板服务，它抱怨找不到耙〜> 1.1.0，所以我安装了。
现在我得到以下错误：
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)
机架清晰安装。 读完这个问题后，我甚至删除了机架1.4.1，只留下了1.1.0，但是我得到了同样的错误。
傀儡仪表盘说10.04 LTS不使用rubygems版本，但是并没有说12.04 LTS的打包版本也不行。
在邮件列表中的一个build议之后，我运行了puppet-dashboard手册中列出的脚本，并将我的gem install降级到了1.3.7。
我也安装了rdocgem。
在这两个变化之间，它解决了这个问题。
在全新安装的Ubuntu 12.04服务器AMD64上，我运行了以下两个命令来获取db:migrate工作：
sudo gem install rack --version=1.1.0 sudo gem install rack --version=1.1.2
除了这个改变之外，我完全按照安装文档工作。 我不知道是否这两个都是必需的，但是第一个只是稍微改变错误信息。 🙂
您可能也对Ruby版本pipe理器感兴趣。 这个工具在同一个盒子上支持多个ruby环境，没有gem冲突。
