回答1:

It looks like setuptoopls is missing. Try

$sudo pip install setuptools

回答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.

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 It was determined I had two packages installed of different versions, both out-of-date.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.

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!
