From: James Britt Date: 2005-02-26T14:55:00+09:00 Subject: Error installing Rails on Win2K I'm trying to update my installation of Rails on a Win2k box, and get this error when the pross gets around to trying to install actionmailer: Attempting remote installation of 'actionmailer' ERROR: While executing gem ... (NoMethodError) undefined method `serialize' for CGI::Session::ActiveRecordStore::Session:Class In the past when I had actionmailer problems when updating Rails (the last three of four times I updated Rails, think) I was told to delete old copies of actionmailer. I've done that again now, but it doesn't help. Anyone know of a way around this error? I could live very happily without actionmailer (none of my code does any mailing), but the Rails gem insists I install it anyway. Thanks, James P.S. I've managed to update Rials on my Linux box with no problem. Is there a way to just copy over a gem installed on one machine to another? I tried just copying the gem subfolder folder with the actionmailer lib files in them, but it didn't work. When I tried to install Rails it acted as if actionmailer was not installed.
