Based on the output, it looks like you have artifacts from the old wagtaildemo. That file does not exist in the new repo.
The ‘demo’ virtualenv above was created new, and populated as shown above.
Right. Inspecting the output you posted, it looks as though you cloned the other wagtail demo repo, built it, and reported an error for it in this repo.
For instance, your output from pip install -r requirements.text lists libraries that do not exist in the requirements file in this repo.
You are right, I have confused the bakery demo with the orig wagtail demo. Will close this issue here.
