安装pbr时出现错误

Question

我想在运行OSX 10.8.5的计算机上安装Openstack客户端。作为前提条件，我需要安装pbr。因此，我进行了以下操作：

git clone git://github.com/openstack-dev/pbr.git
cd pbr
sudo python setup.py install

但我得到了以下错误跟踪

Traceback (most recent call last):
  File "setup.py", line 22, in <module>
    **util.cfg_to_args())
  File "/Users/jimcgh/dev/pbr/pbr/util.py", line 241, in cfg_to_args

    "git --git-dir=\"" + git_dir + "\" describe --always").replace(

    raise child_exception
TypeError: must be encoded string without NULL bytes, not str

如何解决这个问题？

请帮忙。 谢谢您

Answer 1

这是因为git仓库中的构建处于开发中，可能有bug。我使用pip从稳定发布版本（在pypi上）安装了pbr，方法如下：

sudo easy_install pip # if you don't already have pip
pip install pbr

如果您有easy_install或pip，请按照此教程操作。

如果您不想使用像easy_install或pip这样的软件包管理器。 那么您可以前往PyPI页面，并下载tarball文件。只需提取tarball文件并在pbr包内运行python setup.py即可。但安装pip将为您节省很多麻烦。
