Exception raised: module 'subprocess' has no attribute 'mswindows'

[Jan Collijs]

Running archlinux installed through pip:

pip install python-openstackclient
python-openstackclient==1.7.1

I get the error "Exception raised: module 'subprocess' has no attribute 'mswindows'" when trying to run the openstack command..

thats a bit rough, considering subprocess is standard lib, can you try running a command with --debug and attach the output, sounds like it's specific to archlinux

When entering a command like 'openstack server list' or 'openstack --help' everything is working fine so it seems. When running the command 'openstack' it goes into this error state:

okay, looks like in py35 subprocess was renamed,

openstackclient depends on cliff, which depends on cmd2, and it looks like doug hellman already created a pull request to fix the issue here: https://bitbucket.org/catherinedevlin/cmd2/pull-requests/8/fix-bug-18-by-using-sysplatform-instead-of/diff

we'll need all of those previous bits released before we can get this resolved in openstackclient

[Vincent Legoll (vincent-legoll)]

Looks like its subprocess.mswindows which has been renamed

This is now causing cliff to fail py35 unit tests :(
