Could someone help me out to understand why waf module is not installed in my directory?

waf build system was removed in version ns-3.36:

It is replaced by ns3 script which is a Python script providing an interface similar to waf. Most common commands such as ./waf configure and ./waf build are replaced with almost identical ./ns3 configure, ./ns3 build etc. Internally, however, CMake build system is used.

You can see the merge request which introduced the change here:

Try using the ./ns3 command instead of ./waf
