New year, New job, New laptop.
As part of the fun and games when changing job I’ve been handed a windows laptop and rather than immediately running off and installing a Linux distro or whining till they gave me a mac I decided to stick with it. Unfortunately due to $Reasons, upgrading to Win10 anniversary edition to make use of the windows subsystem for linux is also out :(
Cygwin to save the day
So after installing all the usual tools I found I need to be able to work with ansible for which there is no windows binary and rather than having to bother with jumping onto a local vm every time I wanted to play with it I figured it can’t be that hard to get working … and it wasn’t except for one little package.
When attempting to run
pip install ansible the cryptography dependency kept
bombing out on install

Fortunately this was quickly remedied by a quick
pip uninstall ciff followed by
pip install ansible
I’ve not yet bothered to dig into how I managed to break the cffi package but a quick reinstall did the job and I can now ansible locally to my hearts content.
