How to update gems in Ruby for Windows?

Question

I\'m using Ruby\'s Command prompt. I cannot install any update, but internet navigation seems to be working.

I have no proxy here.

Answer 1

First run (with administrator privileges):

gem update --system

Then run the update for activesupport. I have that error one time, because i was behind a proxy, in that case, put:

gem update --http-proxy http://web.proxy.uri --system
