Question

我在ubuntu 12.04中使用ns-3.16。我是python以及ns3的新手。当我运行./waf（或任何其他waf命令）时，它会生成以下代码：

   Waf: Entering directory `/home/hp/ns-3.16-git-master/build'
Waf: Leaving directory `/home/hp/ns-3.16-git-master/build'
Traceback (most recent call last):

    dst_node = ns3_dir_node.find_or_declare(src_node.name)
AttributeError: 'NoneType' object has no attribute 'find_or_declare

我该如何解决这个问题？

Answer 1

这只是意味着你的ns3_dir_node是None。因此它没有find_or_declare方法。您必须查看脚本以找出ns3_dir_node id为无原因的原因。

./waf命令不起作用
