There is something wrong with your Python 3.4. What happens if you just do
$ /usr/local/bin/python3.4 >>> import os >>> import _collections_abc and $ /usr/local/src/mailman-bundler/venv-3.4/lib/python3.4 >>> import os >>> import _collections_abc I suspect you will get ImportError on all of those which means your Python 3.4 install is broken. You need to have a working Python 3.4 that can successfully import os -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1445764 Title: "The executable /usr/bin/python3.4 does not exist" error when Installing Mailman 3 on Centos 7 To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1445764/+subscriptions _______________________________________________ Mailman-coders mailing list [email protected] https://mail.python.org/mailman/listinfo/mailman-coders
