For the time being, try using the above approach. There’s some clashing going on with some dependencies, and the docker image seems to take care of it manually with this line:
sed -i.bak s/==1\.0b1/\>=1\.0\.2/g /usr/lib/python3.*/site-packages/merkletools-1.0.2-py3.*.egg-info/requires.txt
Alternatively, another approach is to manually update chainpoint’s dependency to 1.0.3. Unfortunately I do not know why it’s trying to use a previous version of merkeltools.
vi /usr/local/lib/python3.6/site-packages/chainpoint-0.0.2.dist-info/METADATA
Change to merkletools (==1.0.2) to merkletools (>=1.0.3)
