I was trying to install some requirements of a project whose results I wanted to reproduce locally in a conda virtual environment (Windows 10, Python 3.6). However I keep getting these errors while installing bcolz, first building wheels fails and running setup.py clean fails. Some of the lines from the first error aren't visible in the command window.

My attempts to solve this: I searched for failed to build wheel for bcolz and I found zipline installation error : failed building wheel for bcolz which from the logs posted seems to be different. From the missing file "io.h" and the post Cannot open include file: 'io.h': No such file or directory I figured it might be a build tools problem so I uninstalled and reinstalled build tools from the Visual Studio installer, also tried pip install buildtools, but nothing changed (I do have Windows 10 SDK installed). My next attempt was after reading the answer that said the INCLUDE path needs to be updated with the path containing io.h, although that didn't change anything either. I don't have any more ideas about how to solve this error, would be grateful for help.
