I suspect this is my ineptitude in getting path variables set right, but I\'m at a loss.
I\'ve installed the aws cli using pip in cygwin.
pip install aws
Adding my fix, for people who are facing this issue in Anacond2
After you install anaconda2 , run this command in cygwin (suppose you have installed it at c:\anaconda2)
echo "PATH=\$PATH:/cygdrive/c/anaconda2" >> .bash_profile
echo "PATH=\$PATH:/cygdrive/c/anaconda2/Scripts" >> .bash_profile
source .bash_profile
