Travis build and test fails

Created by: yookoala

Travis uses virtualenv in an isolated manner.

This approach provides flexibility for Python package to test against different Python versions. However, this approach prevents running python test with system pacakges (e.g. python-gi) and globally installed packages (e.g. pycangjie). Even if the flag –system-site-packages is on, system package cannot be found normally.

Autoconf also falls short in Travis environment. Builds sometimes use Python 3.2 (/opt/python/3.2.6/bin/python3.2) and sometimes uses Python 3.5 (/opt/python/3.5.2/bin/python3.5). After a long period of test, I fail to find any solution for testing natively on Travis image.
