Hello G.s ``` I am beginner in ROR. I have an application built in rails v ``` 1.2.4 or 1.2.6, whenever I’ll start the webrick server its give me an error “reqire\_gem”. As per my understanding there is an issue of version or may be there is a plugin who use the “require\_gem”. ``` I tried at my level best, done the necessary changes like gem ``` update, boot.rb replace the “requiregem” etc. But still don’t get at any success. Thanks amshah ---

Can you suggest me which version i have to install so that the error require\_gem and activesupport resolve. I have install the older version of ruby 1.6.8, But now i am unable to run the gem command(rails). Please help me. Thanks amshah
