OpenStack DevStack安装Ubuntu16.04

Question

我试图在Ubuntu16.04桌面的干净安装上安装OpenStack DevStack。

当遇到以下错误时，设置将停止：

+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

我还看到了许多关于Python版本的警告：

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.

我正在运行Python2.7.12和3.5.1-3

我用sudo useradd -d /bin/bash -d /opt/stack -m stack设置了用户

谢谢

在某个地方，virtualenv未能将pip和其他python东西安装到~/requirements/..venv/中。对DevStack有更好理解的人应该正确地解决这个问题，但同时手动运行以下命令为我解决了这个问题：

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

在深入研究之后，我发现在脚本使一切正常运行之前，运行下面的代码。只是提醒一下我正在使用16.04：

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

这是很有趣的，因为没有一个指南提到这一点，我认为脚本应该安装这个。我想知道自从最初的16.04版本发布以来，发生了什么变化？

我仍然收到所有Python警告(知道为什么吗？)，但我现在有了一个工作的DevStack环境。
