Ciao a tutti, premetto che sono alle primissime con ruby.  
Ho avuto numerosi problemi per riuscire ad installare con successo la  
libreria curb, per la mancanza di 3 o 4 pacchetti, che dopo svariati  
tentativi e letture dei log ho trovato, e nonostante l’installazione sia  
andata a buon fine, con questo codice:

c = Curl::Easy.perform(“[http://www.officina.netsons.org/ed/index.php](http://www.officina.netsons.org/ed/index.php)”)  
puts c.body\_str

ruby risponde :

################  
uninitialized constant Curl (NameError)  
################

Suppongo la libreria non sia installata correttamente, quindi vi scrivo  
cosa risponde dopo l’installazione al comando gem install curb :

gem install curb  
Need to update 2 gems from [http://gems.rubyforge.org](http://gems.rubyforge.org)  
…  
complete  
Building native extensions. This could take a while…  
Successfully installed curb-0.1.2  
Installing ri documentation for curb-0.1.2…  
Installing RDoc documentation for curb-0.1.2…

Spero possiate aiutarmi.

La libreria è installata correttamente, non l’hai importata:

rhymes@groove ~ % irb

```
    irb(main):001:0> require 'rubygems'

```

=\> true  
irb(main):002:0\> require ‘curb’  
=\> true  
irb(main):003:0\> c =  
Curl::Easy.perform(“[http://www.officina.netsons.org/ed/index.php](http://www.officina.netsons.org/ed/index.php)”)  
=\> #Curl::Easy:0x106c970  
irb(main):004:0\> puts c.body\_str

[...]
