error: 'Default' is not a member of 'ns3::YansWifiPhyHelper'

Я хочу скомпилировать файл "third.cc" на симуляторе ns3.33 и у меня возникает ошибка: error: 'Default' is not a member of 'ns3::YansWifiPhyHelper' 108 | YansWifiPhyHelper phy = YansWifiPhyHelper::Default (); | ^~~~~~~ Build failed -> task in 'third' failed with exit status 1 (run with -v to display more information)

How I can solve this ?

I have used ubuntu 20.04.2 LTS and python3 package ns3.33 simulator.
