Ecco cosa. prima ho fatto:Errore durante l'installazione di Ruby 2.2.2 con RVM su Ubuntu 14.04
rvm get stable
rvm install ruby-2.2.2
Nessun accordo. Mi mostra la seguente:
$ rvm install ruby-2.2.2
Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/14.04/i386/ruby-2.2.2.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for ubuntu.
Requirements installation successful.

There was an error(6).

No fallback URL could be found, try increasing timeout with:
echo "export rvm_max_time_flag=20" >> ~/.rvmrc
There has been an error fetching the ruby interpreter. Halting the installation.
ho aumentato il timeout come detto:
echo "export rvm_max_time_flag=20" >> ~/.rvmrc
Ma nessun accordo. Ho anche fatto il rvm get head
e ho fatto tutto da capo con timeout più alti, ma non era ancora buono.
cosa posso fare per installare correttamente ruby-2.2.2 su ubuntu?
Vedere se questo aiuta http://stackoverflow.com/questions/23339379/rvm-fails-installing-ruby –
Non lo fa. Potrebbe essere lo stesso problema. Non sono sicuro però. –
