Hi,
we found a work-around to get it to work on Ubuntu 18.04.4 LTS.
Install the package python-ujson with apt:
sudo apt install python-ujson
Then move the ujson.so file to usjon.old in /opt/minemeld/engine/current/local/lib/python2.7/site-packages
ubuntu@lxminemeld:/opt/minemeld/engine/current/local/lib/python2.7/site-packages$ mv ujson.so ujson.so.old
Link the ujson.so from the apt package
ubuntu@lxminemeld:/opt/minemeld/engine/current/local/lib/python2.7/site-packages$ ln -s /usr/lib/python2.7/dist-packages/ujson.x86_64-linux-gnu.so ujson.so
Restart everything
sudo -u minemeld /opt/minemeld/engine/current/bin/supervisorctl -c /opt/minemeld/sup
ervisor/config/supervisord.conf restart all
Good luck!
Kind Regards,
Edd
