VIM issues with powerline

What to do if you get this annoying issue -

vi requirements.txt Traceback (most recent call last): File "", line 4, in ModuleNotFoundError: No module named 'powerline' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "", line 9, in ModuleNotFoundError: No module named 'powerline' An error occurred while importing powerline module. This could be caused by invalid sys.path setting, or by an incompatible Python version (powerline requires Python 2.6, 2.7 or 3.2 and later to work). Please consult the troubleshooting section in the documentation for possible solutions. Unable to import powerline, is it installed? Press ENTER or type command to continue

It means the your bash uses powerline and within your virtualenv your vim does not find the powerline python modules to exist. hence install powerline-status (yes 'powerline-status', as powerline is taken by some other project) That should resolve the issue
