python - 为什么我不能在OS X上安装openstack nova客户端？

我正在尝试在Mac（10.4.8）上安装openstack nova客户端

nova = https://github.com/openstack/python-novaclient#command-line-api

python --version
Python 2.7.2

我成功安装了nova（after installing pip）

运行客户端时，出现以下错误

foo@bar-macbook-pro:~$ nova
Traceback (most recent call last):
  File "/usr/local/bin/nova", line 6, in <module>
    from novaclient.shell import main
  File "/Library/Python/2.7/site-packages/novaclient/__init__.py", line 15, in <module>
    import pbr.version
ImportError: No module named pbr.version

在我的研究中，我发现有关pbr的信息相互矛盾，有人说它是nova所必需的，而另一些人说它不是nova所必需的。

尝试安装pbr时，出现以下错误。

foo@bar-macbook-pro:~$ sudo python ~/Downloads/pbr/setup.py  install
Traceback (most recent call last):
  File "setup.py", line 22, in <module>

有什么明显的东西可以解释为什么我无法安装该库吗？

当然，我一定不是第一个尝试在OS X上安装nova的人。

最佳答案

一年多以后，我终于在OS X Yosemite上开始工作了

sudo pip install python-novaclient

我不必安装pbr。
