Question

我正在尝试运行rails console。我已经尝试了所有建议的SO。我安装了libreadline-6。我的ruby版本是2.1.1，irb是0.9.6。

/home/xamroc/.rbenv/versions/2.1.1/lib/ruby/2.1.0/irb/completion.rb:9:in `require': cannot load such file -- readline (LoadError)
from /home/xamroc/.rbenv/versions/2.1.1/lib/ruby/2.1.0/irb/completion.rb:9:in `<top (required)>'
from /home/xamroc/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.0.3/lib/rails/commands/console.rb:3:in `require'
from /home/xamroc/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.0.3/lib/rails/commands/console.rb:3:in `<top (required)>'
from /home/xamroc/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.0.3/lib/rails/commands.rb:51:in `require'
from /home/xamroc/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.0.3/lib/rails/commands.rb:51:in `<top (required)>'
from bin/rails:4:in `require'
from bin/rails:4:in `<main>'

有什么建议吗？

另外，我使用rbenv来管理我的ruby版本。

您需要安装libreadline和-dev包，然后需要重新编译ruby。当你使用rvm时，你应该总是运行

rvm requirements

首先下载并编译ruby。如果您使用rvm，那么您可以运行

rvm reinstall <version>

这样做。

Rails控制台即使在更新后也无法运行
