OS: ubuntu 16.04
python version: 2.7
I am following the instructions from here : https://github.com/ethereum/pyethapp/wiki/Getting-Started
pyethapp from Github. However when I tried to run
pyethapp, it shows this error message:
"sorry, but this version only supports 100 named groups"
AssertionError: sorry, but this version only supports 100 named groups
I know this has something to deal particularly with my machine and regex but I am unable to solve it.
