Travis enables different Python versions through virtual environments, but it seems that there is a little caveat when we try to create Zulip's virtual environment by referring Travis' virtual environment; Zulip's virtual environment refers the system Python. We encountered this behaviour when we tried to run our backend test suite under Python 3.5 in Travis. 'python3 --version' command before activating Zulip's virtualenv showed 'Python 3.5.3' and after it showed 'Python 3.4.3'. This happened when we created the virtual environment using 'virtualenv -p python3'. The solution seems to be to explicitly give the path of the Python interpreter in the Travis' virtual environment using 'which python3'.
