--- BEGIN ISSUE ---
Exception on startup (pygments_cache)
<!--- Provide a general summary of the issue in the Title above -->
<!--- If you have a question along the lines of "How do I do this Bash command in xonsh"
please first look over the Bash to Xonsh translation guide: http://xon.sh/bash_to_xsh.html
If you don't find an answer there, please do open an issue! -->

## xonfig
<!--- Please post the output of the `xonfig` command (run from inside xonsh) so we know more about your current setup -->

## Expected Behavior
<!--- Tell us what should happen -->

## Current Behavior
<!--- Tell us what happens instead of the expected behavior -->
<!--- If part of your bug report is a traceback, please first enter debug mode before triggering the error
To enter debug mode, set the environment variable `XONSH_DEBUG=1` _before_ starting `xonsh`.  
On Linux and OSX, an easy way to to do this is to run `env XONSH_DEBUG=1 xonsh` -->

## Steps to Reproduce
<!--- Please try to write out a minimal reproducible snippet to trigger the bug, it will help us fix it! -->
