How to check if gems is installed

Rails
1

Hi all,

I use one-click installer to install ruby, together with gems under my
vista box.
I can type “ruby -v” from any directory and the promt windows shows
ruby 1.8.6 after setting the enviroment variables. But I can only check
“gems --version” in this directory c:\ruby\bin. Is it possible to check
“gems --version” from other directories? and how?

thank you very much,
Li

Try gem --version, not gems.

It doesn’t work either.

Then you might not have the ruby folder on the PATH variable in windows.

Right-click My Computer → Properties → Advanced → Environment
Variables
and add the path to ruby at the end of the PATH.

I have no problem check ruby version and gem version from any directory
when I install Ruby on window XP after I add the path to the system
environment. But I now I follow the same method to install Ruby on
Vista. I can check ruby version from any directory after adding the path
to the system environment variable BUT NOT that of gem. I went to gems’
website, which suggests to add RUBYOPT variable with value as rubygems.
I follow it and it doesn’t work either.

I wonder if there is some compatibility Ruby with Vista.

Thanks,

Li
