侨民管理设置失败

Question

在创建了一个pod之后，我尝试通过运行以下命令来设置管理用户：

DB=postgres bundle exec rails console production

但失败的原因是：

/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 /home/diaspora/.rvm/rubies/ruby-2.0.0-p481/lib/ruby/2.0.0/irb/completion.rb:9:in `<top (required)>'
from /home/diaspora/.rvm/gems/ruby-2.0.0-p481@diaspora/gems/railties-3.2.18/lib/rails/commands/console.rb:3:in `require'
from /home/diaspora/.rvm/gems/ruby-2.0.0-p481@diaspora/gems/railties-3.2.18/lib/rails/commands/console.rb:3:in `<top (required)>'

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

有人知道怎么克服这件事吗？

您需要安装一个具有Readline支持的Ruby。查找libreadline-dev、libreadline-devel或类似的包。安装之后，运行rvm reinstall 2.0。
