There is a solution for my problem, enter the link here

Perhaps this is most important (instead of python2.X enter your python ver. python2.7 ) export PYTHONPATH=$HOME/.local/lib/python/site-packages:$PYTHONPATH
export PYTHONPATH=$HOME/.local/lib/python2.X/site-packages:$PYTHONPATH
export PATH=$HOME/.local/bin:$PATH

Setting this worked for me,

 sudo apt-get install libevent-dev sudo apt-get install python-all-dev

and then

 pip install greenlet pip install gevent
