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
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)

not getting whats happening.???

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

./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!

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

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