There is no such file to download - readline (Download error)

Question

When I want to start the Rails 3 console, it calls the following:

$ script/rails c /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (Load Error) 

I tried installing libreadline-dev :

 $ sudo wajig install libreadline-dev Leyendo lista de paquetes... Hecho Creando árbol de dependencias Leyendo la información de estado... Hecho Se instalarán los siguientes paquetes extras: libncurses5-dev libreadline6-dev Se instalarán los siguientes paquetes NUEVOS: libncurses5-dev libreadline-dev libreadline6-dev 0 actualizados, 3 se instalarán, 0 para eliminar y 6 no actualizados.

But when I tried again, it throws the same thing again:

 $ script/rails c /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError) from /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `require' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `<top (required)>' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `require' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' 

Then I try to install readline using rvm :

 # rvm pkg install readline Fetching readline-5.2.tar.gz to /usr/local/rvm/archives Extracting readline-5.2.tar.gz to /usr/local/rvm/src Applying patch '/usr/local/rvm/patches/readline-5.2/shobj-conf.patch'...

Configuring readline in /usr/local/rvm/src/readline-6.2. Compiling readline in /usr/local/rvm/src/readline-6.2. Installing readline to /usr/local/rvm/usr 

But again the same thing:

 $ script/rails c /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError) from /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `require' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `<top (required)>' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `require' from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' 

What else should I try?

Answer 1

I have to check rvm requirements and make sure all packages are installed. Then repeat ruby:

 rvm reinstall 1.9.2 Removing /usr/local/rvm/src/ruby-1.9.2-p318... Removing /usr/local/rvm/rubies/ruby-1.9.2-p318... Removing default ruby interpreter Removing ruby-1.9.2-p318 aliases... Removing ruby-1.9.2-p318 wrappers... Removing ruby-1.9.2-p318 environments... Removing ruby-1.9.2-p318 binaries... Installing Ruby from source to: /usr/local/rvm/rubies/ruby-1.9.2-p318, this may take a while depending on your cpu(s)... ruby-1.9.2-p318 - #fetching ruby-1.9.2-p318 - #extracting ruby-1.9.2-p318 to /usr/local/rvm/src/ruby-1.9.2-p318 ruby-1.9.2-p318 - #extracted to /usr/local/rvm/src/ruby-1.9.2-p318 ruby-1.9.2-p318 - #configuring ruby-1.9.2-p318 - #compiling ruby-1.9.2-p318 - #installing Removing old Rubygems files... Installing rubygems-1.8.18 for ruby-1.9.2-p318 ... Installation of rubygems completed successfully. ruby-1.9.2-p318 - adjusting #shebangs for (gem irb erb ri rdoc testrb rake). ruby-1.9.2-p318 - #importing default gemsets (/usr/local/rvm/gemsets/) Install of ruby-1.9.2-p318 - #complete 

And finally it works:

 $ script/rails c DEPRECATION WARNING: railtie_name is deprecated and has no effect. (called from <top (required)> at /home/israel/proyectos/d-Formacion/config/application.rb:7) /usr/local/rvm/gems/ruby-1.9.2-p318/gems/actionpack-3.0.4/lib/action_dispatch/http/mime_type.rb:98: warning: already initialized constant PDF Loading development environment (Rails 3.0.4) 1.9.2-p318 :001 > exit 

Answer 2

reinstalling ruby ​​is a bit of a bust, you can follow the instructions in this blog post.

http://vvv.tobiassjosten.net/ruby-on-rails/fixing-readline-for-the-ruby-on-rails-console

install libreadline5 and libncurses5

 $ sudo aptitude install libreadline5-dev libncurses5-dev 

then rebuild and reinstall redline

 cd ~/.rvm/src/ruby-1.9.2-p180/ext/readline ruby extconf.rb make make install 

Answer 3

The solution combines two stages:

• Install libreadline-dev, e.g. on Ubuntu do:

   sudo apt-get install libreadline-dev 

• Reinstall Ruby

   rvm install 1.9.2 

Then ruby ​​will be compiled using libreadline.
