使用 devstack 安装 shell 脚本安装了 openstack，但尝试打开仪表板时出现 500 错误

我按照以下说明进行操作http://devstack.org/guides/single-machine.html安装 OpenStack。

我首先使用官方支持的 Ubuntu 12.04 LTS Windows 安装程序在 Windows 7 PC 上安装了 Ubuntu。然后我按照上述页面上的说明安装 OpenStack。

根据说明，我应该能够访问仪表板，又名 Horizo​​n http://192.168.1.4/（这是我安装 Ubuntu->OpenStack 的 PC 的 IP）。

然而，当我打开它时，出现了一个 500 错误网页。

我该如何解决此错误？我想为 OpenStack 设置一个开发环境。

供您参考，现在给出了完整的错误信息--

这是一个漏洞在 devstack 中支持量子节点和 nodejs（但可能在 horizo​​n 中得到修复）。鉴于我尝试做和你一样的事情（在 VM 中），我通过以下方式让 horizo​​n 工作：

  1. sudo su
  2. cd /usr/bin
  3. ln -s nodejs node

node这将创建指向的符号链接nodejs。假设所有其他条件都相同，horizo​​n 现在应该可以正常启动。
