tale file da caricare - readline (Load Errore)

Question

Quando voglio eseguire Rails 3 console, getta questo:

$ 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) 

ho provato ad installare libreadline-dev:

$ sudo wajig install libreadline-dev

Ma quando ho provato di nuovo, si getta tha stessa cosa di nuovo:

$ 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>' 

Poi, provo ad installare readline utilizzando 012.323.957.014.:

# 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

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 

Ma ancora una volta la stessa:

$ 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>' 

Che altro dovrei provare?

Answer 1

Devo controllare rvm requirements e verificare che tutti i pacchetti siano stati installati. Poi reintall rubino:

rvm reinstall 1.9.2

ruby-1.9.2-p318 - #importing default gemsets (/usr/local/rvm/gemsets/) 
Install of ruby-1.9.2-p318 - #complete 

Infine così:

$ 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

Answer 2

La soluzione è combinare le due fasi:

1. Installare libreadline-dev esempio su un'Ubuntu fare:

   sudo apt-get install libreadline-dev 
   

2. Reinstallare Rubino

   rvm install 1.9.2 
   

Poi rubino saranno compilati utilizzando libreadline.

Answer 3

reinstallazione rubino è un tipo eccessivo, è possibile seguire le istruzioni su questo post del blog.

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

installare libreadline5 e libncurses5

$ sudo aptitude install libreadline5-dev libncurses5-dev 

poi ricostruire e reinstallare Redline

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