Missing libpython2.7.so.1.0 on Python 2.7.13 Heroku dynos

Question

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> 2017-06-30T10:56:05.825694+00:00 app[web.1]: import cdbg_native as native 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.

You may refer to the solution presented in the reply to the libpython2.7.so.1.0: cannot open shared object file: No such file or directory . 1 "Try to find file libpython2.7.so.1.0: locate libpython2.7.so.1.0 In my case, it show out put: /opt/rh/python27/root/usr/lib64/libpython2.7.so.1.0 Then add dir /opt/rh/python27/root/usr/lib64 to file /etc/ld.so.conf And run ldconfig".
