DevStack安装错误：目录'opt/stack/nova'不可安装

Question

我正在虚拟机中用Ubuntu 14.04安装Devstack。当我运行命令./stack.sh时，脚本运行了一段时间后，终端就出现了这个错误：

   DEPRECATION: --no-install, --no-download, --build, and --no-clean are deprecated.  
   See https://github.com/pypa/pip/issues/906.
   Directory '/opt/stack/nova' is not installable. File 'setup.py' not found.
   Storing debug log for failure in /home/name/.pip/pip.log

pip.log文件显示：

    /usr/local/bin/pip run on Thu Aug 14 16:53:09 2014
    DEPRECATION: --no-install, --no-download, --build, and --no-clean are deprecated.
    See https://github.com/pypa/pip/issues/906.
    Directory '/opt/stack/nova' is not installable. File 'setup.py' not found.
    Exception information:

    File "/usr/local/lib/python2.7/dist-packages/pip/commands/install.py", line 260, 
    in run

    InstallRequirement.from_editable(name, default_vcs=options.default_vcs))
    File "/usr/local/lib/python2.7/dist-packages/pip/req.py", line 114, in from_editable
    name, url, extras_override = parse_editable(editable_req, default_vcs)
    File "/usr/local/lib/python2.7/dist-packages/pip/req.py", line 1693, in 
    parse_editable
    raise InstallationError("Directory %r is not installable. File 'setup.py' not 
    found." % url_no_extras)
    InstallationError: Directory '/opt/stack/nova' is not installable. File 'setup.py' 
    not found.

如果需要，我可以提供更多细节，任何帮助都非常感谢。

试试下面的命令。这些应该能让你开始工作。

sudo rm -rf /opt/stack/nova

sudo apt-get purge python-paste

sudo apt-get install python-paste

sudo apt-get purge python-pastedeploy

sudo apt-get install python-pastedeploy

再执行一次 unstack.sh 和 stack.sh。
