My ruby applications have suddenly stopped running on my PC. It looks like the gem libraries are no longer in the path. My gems are installed to this directory C:\ruby\lib\ruby\gems\1.8\gems\ I never had to setup a manual path for this, it was "auto-magically" handled by Ruby. Any ideas what would cause this to just quit working like this and how to fix it? Is there some Ruby config file that loads the paths etc... Thanks! ---

Libraries in the gem directories need to use the RubyGems runtime to find them. The one click installer implicitly loads RubyGems by setting the RUBYOPT environment variable to 'rubygems'. Is is possible this environment variable is no longer set? > **···** > > --- > -- Jim Weirich > > -- > Posted via [http://www.ruby-forum.com/\](http://www.ruby-forum.com/%5C). ---

Jim, Thanks for the help! The RUBYOPT environment variable must be set behind the scenes somewhere. I did not have it set in my Windows environment variables previously, but had just recently added it and set it to "w" to get more detailed warning messages. After changing this to "rubygems" everything worked great again. Joe ---

How do you put two options in RUBTOPT? What's the delimiter? For example, what if I wanted both "rubygems" and "w"? "rubygems w" and "rubygems, w" don't work under Windows in Ruby 1.8.4. > **···** > > On 3/1/06, Joiey.Seeley@gmail.com \ wrote: > > > Jim, > > > > Thanks for the help!

If you want to put multiple options in RUBYOPT then you must use the "-" character on the options. So, in this case you'd have to set it to "-rubygems -w".
