How to update Cocoapods

Caution about updating Cocoapads

When we use Cocoapods, sometimes we'll find error like this

[!] The master repo requires CocoaPods 0.32.1 -

You may installed two or three Cocoapads into /Users/name/.rbenv/shims/ or somewhere.

Once you should checked PATH using a command type -a pod.
Then it'll show like

/Users/name/.rbenv/shims/pod
/usr/bin/pod

So you should delete /usr/bin/pod(older one).

After that, once shutdown your terminal, then it'll be updated.(Don't forget to set new PATH)
