I installed rubyinstaller-1.9.2-p290.exe on my Vista system then\ninstalled rails 2.3.8 from a command line window as follows:\ngem install -v=2.3.8 rails\n\nThe installation went fine and a bunch of other gems and rdocs were\nadded to my base Ruby install. However, I can access all the rdocs\nexcept rails 2.3.8. Its doc directory contains empty rdoc and ri\nfolders.\n\nIs there a way I can install the rails 2.3.8 rdoc manually? Any\nassistance greatly appreciated. Thanks.
