below list versions:

(cloudify)ubuntu@ip-172-30-2-253:~$ python --version python 2.7.6  (cloudify)ubuntu@ip-172-30-2-253:~$ pip --version pip 1.5.4 /home/ubuntu/cloudify/local/lib/python2.7/site-packages (python 2.7)  (cloudify)ubuntu@ip-172-30-2-253:~$ virtualenv --version 1.11.4

it seems lack prerequisites.

i suggest check of followings:

  1. update system 

    $sudo apt-get update

  2. install needed libraries 

    $sudo apt-get install python-dev gcc

  3. update pip version 

    $sudo apt-get install pip

  4. update virtualenv version 

    $ sudo pip install virtualenv

after checked should try install cloudify: 

    $pip install cloudify==3.2.1
