We use the original Python2 + + robotframework selenium2 - ride1.5, now want to upgrade Python3 + + robotframework selenium3 - ride1.7, so in the computer installed Python3 and selenium3 + robotframework - ride, environment variables also switch to Python3, but in the open ride. Py file is always opened Python2 old version, don't know what's the matter, in pycharm is normal, when they open the CMD or run directly ride. Not a py,,, and found that run CMD Python3 ride, inside of the from robotide import main the robotide pointing Python2 bag, a great god know what's the problem? Can keep the two versions at the same time?
