I’m not the best person to answer Windows questions. Haven’t used it for a good long while. (emphasis on the ‘good’) But if you know the url for your proxy, you can set up gem to go through it Look here: [http://docs.rubygems.org/read/chapter/13](http://docs.rubygems.org/read/chapter/13) in section 5.10 -sean Hari N. wrote: > Hi > I am getting the following error when i tried to install rails in > windows using command prompt… > > Attempting remote installation of ‘rails’ > Updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org) > ERROR: While executing gem … (Gem::RemoteSourceException) > Error fetching remote gem cache: getaddrinfo: no address associated > with hostname. > > There are proxy settings in my institute and i need to set it up from > the command prompt? pls explain with an example… > > Thanks in Advance… ---

Hi, In Windows, you can directly set the environment variables in the command prompt. Set the variables HTTP\_PROXY, HTTP\_PROXY\_USER and HTTP\_PROXY\_PASS, and then execute “gem install rails --remote”. This should make it work. Thanks!!! ---
