Error: "Could not find 'cocoapods'" while installing a Pod

Question

I tried to use pod install in my project to implement SDK but it throws this error:

/Library/Ruby/Site/2.0.0/rubygems/dependency.rb:318:in 'to_specs': Could not find 'cocoapods' (>= 0.a) among 35 total gem(s) (Gem::LoadError) Checked in 'GEM_PATH=/Users/admin/.gem/ruby/2.0.0:/Library/Ruby/Gems/2.0.0:/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0', execute gem env for more information from /Library/Ruby/Site/2.0.0/rubygems/dependency.rb:327:in 'to_spec' from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_gem.rb:64:in 'gem' from /usr/local/bin/pod:22:in `'
