We are running our Python 2.7.13 application on Heroku.
I believe recently Heroku has changed Python runtime defaults from 2.7.13 to 3.6.1 for new application.
So we put python-2.7.13 to runtime.txt file as they recommend but now if we create a new Heroku app and deploy out code to it, it complains that libpython2.7.so.1.0 cannot be found.
Heroku log content:
...
2017-06-30T10:56:05.825667+00:00 app[web.1]:   File "/app/.heroku/python/lib/python2.7/site-packages/googleclouddebugger/capture_collector.py", line 30, in <module>

2017-06-30T10:56:05.825725+00:00 app[web.1]: ImportError: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
We also cannot find libpython2.7.so.1.0 on dynos, heroku run "cd /; find | grep libpython2.7.so.1.0" gives nothing.
