创建 pod 后，我尝试通过运行以下命令设置管理员用户：

DB=postgres bundle exec rails console production

但这失败了：

/home/diaspora/.rvm/rubies/ruby-2.0.0-p481/lib/ruby/2.0.0/irb/completion.rb:9:in `require': cannot load such file -- readline (LoadError)

from script/rails:6:in `require'
from script/rails:6:in `<main>'

有谁知道如何解决这个问题？

你需要安装一个支持 Readline 的 Ruby。寻找一个包libreadline-dev，libreadline-devel或类似的。之后安装运行rvm reinstall 2.0。
