OpenStack DevStack 安装 Ubuntu 16.04

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

当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

某个地方 virtualenv 无法将 pip 和其他 python 东西安装到 ~/requirements/.venv/ 中。对 DevStack 有更深入理解的人应该可以正确解决这个问题，但与此同时，手动运行以下命令为我解决了这个问题：

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

经过一番挖掘，我发现在脚本之前运行以下命令可以使一切正常运行。提醒一下，我使用的是 16.04：

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

有趣的是，没有任何指南提到这一点，我猜想脚本应该安装它。我想知道自最初的 16.04 版本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？），但我现在有一个可运行的 DevStack 环境。

virtualenv只需添加一些详细信息，您在使用该命令时可能会收到一些权限被拒绝的错误。因此，首先授予777目录权限：

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