Hi! I'm not sure of the cause of this problem, but I think that it could be linked to the initialization of Elasticsearch or linked to your Elasticsearch's version. It could also help, this is our forked project: https://github.com/GoSecure/freshonions-torscraper. I updated the installation documentation and if will all of these hints you don't find a solution, just let me know I will try to investigate a little bit more.

I was having that same issue, and when I try to run the elasticsearch_migrate script, it returns:
"ImportError: No module named elasticsearch_dsl.connections"
Though it is located in the venv lib folder, so I don't know if its a change in the program or what.
Eventually, I had to install elasticsearch_dsl from "apt-get", then run the pip install -r requirements.txt from outside of the virtualenv which downgraded the *dsl version, then once again run it from within the virtualenv for all of the services to properly run. Seemed a bit convoluted, but running this on ubuntu18.04, I figured that there were some OS and thirdparty fixes that still need to happen in order for all of the applications to work.

I faced up problems like this few times when I worked on this project. The implementation, the version, and all the structure were pretty capricious. I know that the old version 5.6.6 works pretty well, but if you are able to make works with the version 5.6.10, just let me know it interests me.

Thank's @jeffwcollins !
