Incompatible six versions in adapt-parser and jsonschema

[dhylands]

While executing prepare-base.sh on the new buster image, in particular, thses lines:

_url="git+https://github.com/mycroftai/adapt#egg=adapt-parser"
sudo pip3 install "$_url"

I saw this error message:

jsonschema 3.0.1 has requirement six>=1.11.0, but you'll have six 1.10.0 which is incompatible.

For reference, a larger snippet of the log is this:

Although looking at the filesystem, it appears to have installed six-1.12.0

pi@gateway:/usr/lib$ find . -name '*six-*'
./python3/dist-packages/six-1.12.0.egg-info
./python2.7/dist-packages/six-1.12.0.egg-info

so this may just be a red herring.
