Diaspora管理员设置失败

Question

After creating a pod, I tried to setup an admin user by running:

DB=postgres bundle exec rails console production

but this failed with:

/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>'

Does anyone know how to get past this?

You need to install a Ruby with Readline support. Look for a package libreadline-dev , libreadline-devel or similar. After that is installed run rvm reinstall 2.0 .
