Cocoa Pods Problem

[msayed9]

I'm trying to install the pod but the PureLayout pod version is old in this project,
as i'm using another library -VGParallaxHeader- that uses Pure layout 3
So a conflict happens. Please update your PureLayout to 3.
Thank you
Edit: Here's the error while pod install:

[!] Unable to satisfy the following requirements:

• PureLayout (= 3.0.0) required by Podfile.lock
• PureLayout required by VGParallaxHeader (0.0.6)
• PureLayout (~> 2.0.6) required by BTBalloon (0.1.0)
