In a fresh ruby install you usually have no installed gems. First you might update the gem utility itself to the latest: > gem update --system Then install the gems you need with ‘gem install ’ You can get a list of what gems are available for install with: > gem list --remote rails regards, Janos On Mon, Aug 31, 2009 at 9:05 AM, Abhishek S. \< removed\_email\_address@domain.invalid\> wrote: > my rails apps which i had developed using ruby 1.8.7. > If i have to made any changes in my rails application after installing > ruby 1.9.0 ??? > i am using ubuntu 9.04 and i have installed ruby 1.9.0 in /usr/local/bin > > ## thanx. > > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/). > > > – Ãœdv, Sebi ---

I think your gem program points to gem1.9, and therefore output is empty. If you do “gem1.8 list” you will get all the gems installed with rubu1.8. Also if “ruby -v” outputs ruby 1.9, and you still want to use ruby1.8 then perhaps you need to symlink ruby1.8 to ruby. – अभिनव [http://twitter.com/abhinav](http://twitter.com/abhinav) On Mon, Aug 31, 2009 at 12:35 PM, Abhishek S. \< ---

First of all, I hope you are linux/mac. If yes, google “symlink” or “ln -s howto”. In short, what you need is this: > ln -s file\_you\_want\_to\_symlink new\_path or in your case most probably, it will be > sudo ln -s /usr/bin/ruby1.8 /usr/bin/ruby – अभिनव [http://twitter.com/abhinav](http://twitter.com/abhinav) On Mon, Aug 31, 2009 at 4:14 PM, Abhishek S. \< ---
