Hi, I’m on Windows 2000 with Service Pack 4. Was installing RubyGems and got the error shown below - at the end of this post. Tried it a few times (including uninstalling my complete Ruby installation, in case some files had got messed up), but got the same error each time. The main or only error is at the end of the output, but I’ve shown the full output below. It says: Successfully built RubyGem but then says: hook C:/Temp/inst/rubygems-0.9.4/./post-install.rb failed: install directory #\ not absolute ## Would appreciate any pointers to what the errors might be due to. Interestingly, this the first time this has happened. I’ve been programming Ruby for some time now, and have never had a problem installing either Ruby itself, or RubyGems, earlier. This error happened after I had uninstalled my earlier Ruby version and was installing the latest stable Ruby version, and then the latest stable RubyGem version. Errors while running “ruby setup.rb” (also tried “ruby setup.rb all”) to install RubyGems v0.9.4: [ The error is at the end of the output below - at and below this line: “hook
