Problem installing neutron: ryu… invalid environment marker

I ran into a problem while installing neutron. This error is rather common (as seen through googling) but the solution was hard to find. This is what I found that worked for me. YMMV.

Getting YouTube embedded in IOS 9 using Swift

These are just basic notes for me because I will forget.

This uses the Swift-YouTube-Player Cocoapod from https://github.com/gilesvangruisen/Swift-YouTube-Player

Copy the instructions here to get it installed using pods.

It isn’t up-to-date with swift 2.0 yet so copy the changes here

Then (using the information from here) make sure the VTPlayer.html file is included in the Pods (YouTubePlayer) resources list:

Click on Pods ‘project’
Click on YouTubePlayer under TARGETS
Click on Build Phases
Click on the plus sign (add build phase)
Add a Copy Files build phase
Set Destination to Resources and add the YTPlayer.html file

Rebuild all the things.

Workflow Tip 1: Manual Replaces

These workflow tips are for me to remember how I managed to make certain things more efficient.

This episode started from my local neutron failing to start due to:

2015-03-16 10:56:59.272 6232 CRITICAL neutron [-] ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option

This was caused by this upstream change:

015-03-16 10:56:59.162 6232 TRACE neutron.service from neutron.openstack.common import log as logging

I had to change all the from neutron.openstack.common import log as logging lines to from oslo_log import log as logging. This isn’t a big deal and you’d think sed would work, but it can’t work due to the difficulties involved in reordering the imports into alphabetical order.

Workflow

Using tmux I’d make a vertical split and make my edits in one of the panes. In the other pane I run:

watch -n 1 'find . -name "*.py" | xargs grep "neutron.openstack.common import log as logging"'

Having an updating list of what files I need to update is helpful and keeps me sane.
