i got error
[!] Unable to satisfy the following requirements:
YLProgressBar (~> 3.4.0) required by Podfile

i use #pod search YLProgressBar
can't find version 3.4.0

I use 3.4.0 and I don't have this problem.
Also cocoapods.org shows the correct result:
http://cocoapods.org/?q=ylprogressbar

It might be that your cocoapods configuration somehow uses an older version of the specs repo as source.

Indeed, when I look for the YLProgressBar pod I have this result:

-> YLProgressBar (3.4.0)
   The YLProgressBar is an UIProgressView replacement with an highly and fully customizable
   animated progress bar in pure Core Graphics.
   pod 'YLProgressBar', '~> 3.4.0'

Have you tried to update your cocopod install (gem update cocoapods)? Or may be this is a cache issue?

I update rvm & gem & cocoapod
to solve this problem
thanks for your reply
