Scapy error: no module names pcapy

Question

The code given below is for sniffing a packet from the IP address provided.

from scapy.all import *

sniff(filter="tcp and host 192.168.0.90", count=10)

On running this code the error I am getting is:

Traceback (most recent call last):   File ".\sample.py", line 1, in <module>
    from scapy.all import *   File "C:\Python27\lib\site-packages\scapy\all.py", line 16, in <module>
    from arch import *   File "C:\Python27\lib\site-packages\scapy\arch\__init__.py", line 79, in <module>
    from windows import *   File "C:\Python27\lib\site-packages\scapy\arch\windows\__init__.py", line 23, in <module>
    from scapy.arch import pcapdnet   File "C:\Python27\lib\site-packages\scapy\arch\pcapdnet.py", line 30, in <module>
    import pcapy as pcap ImportError: No module named pcapy

Where am I going wrong? I am using windows 7 for this.
