Ruby: gem update --system gives this ---> ERROR: While executing gem ... (Net::HTTPRetriableError) 302 "Found"

I am trying to install RedMine Project Management tool on W开发者_Go百科indows. When i Try to run this command "gem update --system", i get the following error: ERROR: While executing gem ... (Net::HTTPRetriableError) 302 "Found"

I have tried to look for a solution but in vain.

Could anyone suggest a work around for this?

Note: I guess the proxy could be the issue here......

I'm having the same problem. I found an article here that says you need to do a gem update --system which begs the question how you do a gem update --system when that will also give a 302 redirect.

Not an answer as such but I think it shows that this may not be a firewall issue. If you find out any more info then please let me know.
