ns2模拟器中没有显示输出

Question

#Call the finish procedure after 5 seconds of simulation time
$ns at 5.0 "finish"

#Print CBR packet size and interval
puts "CBR packet size = [$cbr set packet_size_]"
puts "CBR interval = [$cbr set interval_]"

#Run the simulation
$ns run

我正在尝试从此链接执行示例1。但由于某些原因，在终端中输入ns sample.tcl后，只显示'puts'部分并且没有nam输出。
