No module named 'openpyxl' - Python 3.4 - Ubuntu

@zetysz and @Manish already fixed the problem. I am just putting this in an answer for future reference:

  • pip refers to Python 2 as a default in Ubuntu, this means that pip install x will install the module for Python 2 and not for 3

  • pip3 refers to Python 3, it will install the module for Python 3


If you don't use conda, just use :

pip install openpyxl

If you use conda, I'd recommend :

conda install -c anaconda openpyxl

instead of simply conda install openpyxl

Because there are issues right now with conda updating (see GitHub Issue #8842) ; this is being fixed and it should work again after the next release (conda 4.7.6)
