Hi! I have encountered the following error when trying to run provparser on a clean installation of Ubuntu 18.04 (run in a virtual machine).

Do you happen to have any suggestions on how to fix this, please?

It seems like somewhere in rocksdb they use a python3 function which is not compatible with the python2. In another VM I have also tried to make python3 the default version, and installed everything, but when I would try to run provparser I would get an error along the lines of prepare module is not found (I don't have the exact error text but I can redo the installation and paste the error code here)

I switched to python 3.5 and pip 18.1, and it can work. But there are so many errors like this:
