OpenStack DevStack Installation Ubuntu 16.04

  • 772

I'm trying to do an installation of OpenStack DevStack on a clean installation of Ubuntu 16.04 Desktop.

The Setup stops when it comes to the following error:

+inc/python:pip_install:359                env http_proxy= https_proxy= no_proxy= PIP_FIND_LINKS= SETUPTOOLS_SYS_PATH_TECHNIQUE=rewrite /opt/stack/requirements/.venv/bin/pip install -c /opt/stack/requirements/upper-constraints.txt -U pbr
env: ‘/opt/stack/requirements/.venv/bin/pip’: No such file or directory

I also see lots of warnings about Python versions:

Ignoring asyncio: markers 'python_version == "3.4"' don't match your environment

Requirement already satisfied: systemd-python===234 in /usr/local/lib/python2.7/dist-packages (from -c /opt/stack/requirements/upper-constraints.txt (line 401))
You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm running Python 2.7.12 and 3.5.1-3

I setup the user with sudo useradd -d /bin/bash -d /opt/stack -m stack

Thanks

python openstack 16.04

  1. Somewhere virtualenv failed to install pip, and other python things, into ~/requirements/.venv/ . Someone with better understanding of DevStack should solve this properly, but in the meantime manually running the following command solved the problem for me:

    stack@mymachine:~/devstack$ virtualenv ../requirements/.venv/

  2. After some digging around I found that running the following, before the script made everything work OK. Just a reminder that I'm using 16.04:

    sudo apt-get install git python-pip
sudo pip install --upgrade pip

    It's interesting as none of the guides mention this, and I assume the script is supposed to install this. I wonder what has changed since the original 16.04 release?

    I still get all the Python warnings (any idea why?), but I now have a working DevStack environment.

  3. Just adding some details, You might get some permission denied error while using the virtualenv command. So first give 777 permission to the directory:

    $ sudo chmod 777 /opt/stack/requirements/.venv
$ virtualenv /opt/stack/requirements/.venv/
