我正在尝试使用 nodejitsu 部署我的节点应用程序，但在运行“jitsu deploy”时收到错误消息。
相关的错误行是：

所以我按照这里的描述安装了 scons：http ://www.scons.org/doc/2.3.1/HTML/scons-user.html#idm14220792
基本上安装 tar 文件，打开它，然后运行“sudo python setup.py install”
现在当我运行 'scons -v' 它返回：

但是当我再次运行“jitsu deploy”时，我看到了同样的错误。scons 还没有正确安装吗？这是 nodejitsu、scons 或 libxmljs 的问题吗？
