It could import JSONRPC porperly in python3.8,but not 3.7 or 3.6
@nycholas Thanks! Yes,it works when I used the master version. Before,I used the version on pipy,and that version was not up to date.
This solution worked for me with an additional pip install typing-inspect in python 3.7.3. Not sure if this is something wrong with the setup.py or a problem specific to a python version range including 3.7.3, but thought I'd leave a note in case it is helpful.
@mrJeppard yes, it have a problem with setup.py... the depence typing-inspect was added[1][2] after and I didn't update setup.py with them. Let be free to create a new pull request with this modification.
Thank you.
