乘客中丢失的宝石
我的 Rails 2.3.8 应用程序无法启动，因为缺少 gem：Friendly_id。我收到以下错误消息：
Missing these required gems: friendly_id ~> 3.2.1 You're running: ruby 1.8.7.253 at /opt/ruby-enterprise-1.8.7-2010.02/bin/ruby rubygems 1.3.7 at /home/development/.gem/ruby/1.8, /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8 Run `rake gems:install` to install the missing gems.
其中 development 是我运行该应用程序的用户。
我发现在本地 /usr/lib/ruby/gems/1.8/gems 中，我可以使用 sudo gem installFriendly_id 命令将 gem 安装到此目录中。
但我注意到，在 Passenger 从以下位置检索 gem 的路径中： /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems 没有 Friendly_id 宝石。不过，如果没有 sudo，我就无法运行该命令。
现在我知道我必须将 Friendly_id gem 安装到 /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems 目录中，但是我不知道怎么办。
谢谢。
My Rails 2.3.8 app couldn't startup because of a missing gem: friendly_id. I got the following error message:
Missing these required gems: friendly_id ~> 3.2.1 You're running: ruby 1.8.7.253 at /opt/ruby-enterprise-1.8.7-2010.02/bin/ruby rubygems 1.3.7 at /home/development/.gem/ruby/1.8, /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8 Run `rake gems:install` to install the missing gems.
where development is the user I am running the app.
I found that in my local /usr/lib/ruby/gems/1.8/gems I was able to install the gem into this directory using the sudo gem install friendly_id command.
But I noticed that in the path for Passenger to retrieve the gem from: /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems does not have the friendly_id gem. I couldn't run the command without sudo though.
Now I know I gotta install the friendly_id gem into the /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems directory, but I couldn't figure out how.
Thanks.
