Answer 1

It looks like setuptoopls is missing. Try

$sudo pip install setuptools

Answer 2

Notice that setuptools come from /usr/local/lib whereas pkg_resources come from /usr/lib. You must likely have an older pkg_resources through the package system and then a newer setuptools installed by pip.

Delete (or move away) the /usr/local/lib/python2.7/dist-packages/setuptools directory.

In my case i have odoo v10 installed and for any weird reason update or installed a library that stuck my server and not longer to start with XOE.

The error was:

cannot import name py31compat

After 1 hour trying many differents things i decide uninstall:

sudo pip uninstall setuptools

Uninstalling setuptools-40.8.0:   Would remove:
/usr/local/bin/easy_install
/usr/local/bin/easy_install-2.7
/usr/local/lib/python2.7/dist-packages/easy_install.py
/usr/local/lib/python2.7/dist-packages/pkg_resources/*
/usr/local/lib/python2.7/dist-packages/setuptools-40.8.0.dist-info/**

And my service odoo server starts and works fine again!

I encountered a very similar error upon an Ansible run of a refactored OpenShift playbook. The error was discovered once all of the plays were parsed.

"ERROR! Unexpected Exception, this is probably a bug: cannot import name py31compat"

I am using ...

• Ansible 2.5.3
• Python2-2.7.15

I ran the following command to list the location of all of the packages and libraries associated with Python 2. I checked available paths to ensure I had one version of Ansible and one copy of each package installed.

$ python -c 'import sys; print sys.path'

'py31compat' is not a separate module one can download. It is included with the Setuptools package. It was determined I had two packages installed of different versions, both out-of-date. I uninstalled both via pip and installed the latest setuptools version available. No luck.

My solution was to uninstall Ansible and reinstall the same version. This resolved the issue.
