[ndnSIM] Error in installing ndnsim 2.7

[Zeinab Rezaiefar]

Hello,
Thanks for your help. I have changed base.py file according what you said
and I did not receive error when I config, however, when I run the program
with the vis command (./waf --run=ndn-simple --vis) I receive the error as
below:

No visualization support (cannot import name core).
Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File "/home/zeinab/ndnSIM/ns-3/src/visualizer/visualizer/core.py", line
1875, in start
    import sys
RuntimeError: maximum recursion depth exceeded while calling a Python object

may I know that you have not faced the same problem?
thanks
best Zeinab
