“certificate verify failed” error when installing Ruby gems on Windows

Question

I am using a Windows PC running 8.1 and working with Ruby Installer 2.1.5.

While installing a gem I am getting a error:

C:\\> gem install bundle
E         


        

Answer 1

I had this problem, it seems the problem is due to ruby installer version (2...) , I tried version 1.9.3 and the problem was solved.
