OpenStack DevStack 安装 Ubuntu 16.04

Question

我正在尝试在全新安装的 Ubuntu 16.04 桌面上安装 OpenStack DevStack。

出现以下错误时，安装程​​序停止：

+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

我还看到很多关于 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 Python 2.7.12 和 3.5.1-3

我设置用户 sudo useradd -d /bin/bash -d /opt/stack -m stack

谢谢

某处 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可以正确解决这个问题，但同时手动运行以下命令为我解决了问题：

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