installing ruby gems

hi
how to install rubygems after installing ruby1.8.7
installed rubygems also with following commands

wget -c [http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz](http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz)

tar -xvzf rubygems-1.3.1.tgz
cd rubygems-1.3.1
sudo /opt/ruby-1.8.7-p72/bin/ruby setup.rb
   after this once i gave sudo gem update
  sudo: unable to execute /usr/local/bin/gem: No such file or directory
...

  even same for gem -v..

And for some reason you thought it unimportant to list what directory
you were at when issuing those commands?

Sounds to me to like PATH problems to me - I'd check that your new
ruby install is ahead of the existing one in your path (and don't
forget that sudo cleans up environment variables like PATH before it
runs)

Like I said, my guess would be a problem with your $PATH environment
variable, meaning that your shell then looks for ruby, gem etc. in the
wrong place. Having multiple ruby installs (at a guess, one in /usr,
one in /usr/local and one in /opt) is probably adding to the confusion

i get the following error
./lib/rubygems.rb:10:in `require’: no such file to load – thread (LoadError)

whenever i get an error like this, i usually google the exact error message. and most of the time, i get

the solution i need. googling “no such file to load – thread” gave http://www.ruby-forum.com/topic/122700

as the top result. you might want to check that out :slight_smile: Good luck!

thanks jim,

Possibly a networking problem, or a firewall/proxy permission.

Do you use a proxy for internet traffic? Are there firewall rules on it?
