I am currently using PyCharm with Python version 3.4.3 for this particular project.
This PyCharm previously had Python2.7, and I upgraded to 3.4.3.
I am tryi
I have python 2.7, 3.5 and 3.6 in my linux Mint machine for some reasons.
My spyder uses python 3.5 and I had the same issue. What I have done is
/usr/local/lib/python2.7/dist-packagesxlrd (Note that to do this action you have right click and open as root)/usr/local/lib/python3.5/dist-packages or /usr/local/lib/python3.6/dist-packages and paste the folder xlrd over there. It worked for me!!!
This method does not change the default path so that, I can still continue with python 2.7 without any harm(something like SageMath which I use extensively)
