问题 I just went through the install of Ruby 1.7.2 and for some reason I ended up with version 1.3.5 So now when I do this command: gem --version 1.3.5 My thinking is that I have to purge the 1.3.5 version and install the 1.7.2 fresh correct? The funny thing is that I do have 1.7.2 on my file system at /usr/local/rubygems-1.7.2 How do I un-confuse the system into seeing the right version? The whole issue is stemming when I try to install rails by doing this: gem install rails ERROR: Error

问题 I'm trying to use config/environment.rb to install a ruby gem dependency (because I don't have sudo access to our server; ergo, can't just call gem install hpricot ). I've tried including sundry arguments ( :version , :source , :lib ) but I still get rake aborted! no such file to load -- hpricot Update: It turns out that when I remove the plugin which requires hpricot, then I can execute rake gems:install successfully. But that's not very helpful. It means that if I ever move my app, I run
