Installing Cocoapods error (Tools Video)First Week

I use a iMac late 2009 running OSX Yosemite 10.10.5
I’ve managed to download the most current version of xcode that can run on my setup at 7.2.1

When I get to the part where we install Cocoapods through terminal, right after I type the administrator password, I get this message.

ERROR: Could not find a valid gem ‘cocoapods’ (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: tlsv1 alert protocol version (https://rubygems.org/latest_specs.4.8.gz)
Macintoshs-MacBook-Pro:~ macintoshHD$

Is there a place where I can download Cocoapods myself?
