What ruby version do you use? It seems that you use ruby built locally on your machine, don't you?
Could you please run "gem env" command and post it here.

Oleg

dear Oleg,

thank you so much for your advice, here is the information from Setting Ruby SDK and Gems on the Ruby interpereter "RubySDK 1.8.7 (/usr/local/bin/ruby)". so i think, it is the right place to put RubySDK on local mechine. but why when i try to create a project always get this massage error, when i use Windows , there is noi problem.

How did you install your Ruby interpreter: using "apt-get install ruby" and then created symbolic link /usr/bin/ruby1.8 -> /usr/local/bin/ruby
or just built it from sources?

The same question about gem: how did you installed it?

Regards,
Oleg

dear oleg,

nice advice thanks,

install Ruby with this command "

sudo apt-get install ruby ri rdoc mysql-server libmysql-ruby ruby1.8-dev irb1.8 libdbd-mysql-perl libdbi-perl libmysql-ruby1.8 libmysqlclient15off libnet-daemon-perl libplrpc-perl libreadline-ruby1.8 libruby1.8 mysql-client-5.0 mysql-common mysql-server-5.0 rdoc1.8 ri1.8 ruby1.8 irb libopenssl-ruby libopenssl-ruby1.8 libhtml-template-perl mysql-server-core-5.0

but i think i don't use link to "/usr/local/bin/ruby"

install gems with this command "

wget http://rubyforge.org/frs/download.php/57643/rubygems-1.3.4.tgz
tar xvzf rubygems-1.3.4.tgz
cd rubygems-1.3.4
sudo ruby setup.rb"

and link to local
"
sudo ln -s /usr/bin/gem1.8 /usr/local/bin/gem
sudo ln -s /usr/bin/ruby1.8 /usr/local/bin/ruby
sudo ln -s /usr/bin/rdoc1.8 /usr/local/bin/rdoc
sudo ln -s /usr/bin/ri1.8 /usr/local/bin/ri
sudo ln -s /usr/bin/irb1.8 /usr/local/bin/irb
"

this instruction is obtained from "http://www.hackido.com/2009/04/install-ruby-rails-on-ubuntu-904-jaunty.html"

then, what should i have to do ?

Regards,
Hendri

Let me reinstall ruby environment the way you have described and check then, I will post result asap.

Regards,
Oleg

Hello Hendri,

I've installed ruby as described in http://www.hackido.com/2009/04/install-ruby-rails-on-ubuntu-904-jaunty.html, but couldn't reproduce your problem.
Could you please provide some steps on "how did you setup Ruby SDK"?

Regards,
Oleg

Oleg,
His symbolic links are wrong.  Please see the following article from Peter Cooper:

http://www.rubyinside.com/how-to-install-a-ruby-18-stack-on-ubuntu-810-from-scratch-1566.html

As shown in the article, he needs to create links shown below:

ln -s /usr/bin/ruby1.8 /usr/bin/ruby
ln -s /usr/bin/rdoc1.8 /usr/bin/rdoc
ln -s /usr/bin/irb1.8 /usr/bin/irb

If he has installed Ruby showing the commands that he does then it is not installed in /usr/local/bin, it is installed in /usr/bin.

I am on Ubuntu 8.10.

ln -s /usr/bin/ri1.8 /usr/bin/ri
