python-magnumclient not installing under devstack

[Paul Michali]

Using the Getting Started directions on Ubuntu 14.04 (both bare metal and VM on MacOS), when DevStack is processing, the following error message is seen:

2016-11-15 19:28:32.583 | [ERROR] /home/pcm/devstack/inc/python:221 The following LIBS_FROM_GIT were not installed correct: python-magnumclient

Looking in /usr/local/lib/python2.7/dist-packages/ there is an egg file for the client (nothing else). Doing "pip show python-magnumclient" does not show this package.

I had tried RHEL7 and Ubuntu 16.04, both on bare-metal, and did not see this issue.

It seems that it is not a magnum issue. From what I can tell, during stacking, it tries to remove the existing Python-magnum client, and fails (saying no files found). It then says install is successful, but it has not installed the client.

I can manually pip install the client, but then, when stacking, it will fail, as it is looking to see that it is installed, and is installed via git (-e git).

Not sure how to resolve the issue, or how to make the process more robust, but that seems to be the issue that I'm seeing on (coincidentally) two Ubuntu 14.04 systems.

@pcm, I tried installing again using the dev guide and i could successfully install over Ubuntu 14.04.

<<< it tries to remove the existing Python-magnum client, and fails (saying no files found). It then says install is successful, but it has not installed the client.

>> I also got this but still magnumclient got installed, this may be because it's installed from git:

But as you said you faced the issue on Two systems, then there may be some differences between your and mine environment.
Have you done anything apart from referring the dev guide,

Not sure, but may be setuptools issue:-

Can you check version in your environment. I saw a similar bug in setuptools 25(reference: https://review.openstack.org/#/c/346545/). May be Spyros can give more input here.
