在Ubuntu 12.04上安装Ruby 1.9.3时出错

Question

I already have ruby-2.0.0-p0

And I am trying to install Ruby 1.9.3

rvm install ruby-1.9.3-p448

Facing following error

Searching for binary rubies, this might take some time.

No binary rubies available for: ubuntu/12.04/i386/ruby-1.9.3-p448.

Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

Checking requirements for ubuntu.

Requirements installation successful.

curl: (6) Couldn't resolve host 'www.dnsbalance.ring.gr.jp'

There was an error(6).

Checking fallback: http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p448.tar.bz2

Checking fallback: http://www.mirrorservice.org/sites/ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p448.tar.bz2

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.

Answer 1

try to do this things:

• ping ftp.ruby-lang.org
• rvm reload .
• sudo /etc/init.d network restart

Maybe it helps you understand where is problem.

You always can uninstall 2.0.0 and install 1.9.3 and 2.0.0 again or reinstall rvm ( but it's not good way )
