ImportError: No module named scapy.all

问题:

I'm running macOS Sierra and Python 2.7.

In my terminal I've installed scapy with:

pip install scapy
Requirement already satisfied: scapy in /usr/local/lib/python2.7/site-packages

But running this:

from scapy.all import *

for pkt in sniff(iface='en0'):
    print pkt

Gives me this:

python test.py 
Traceback (most recent call last):
  File "test.py", line 1, in <module>
    from scapy.all import *
ImportError: No module named scapy.all

I've tried and Google around, and installed pcapy and other packages - but no luck.

ImportError: No module.. found error happens when Python doesn't find your module. So, where does it look for modules?

import os
print os.sys.path

Verify /usr/local/lib/python2.7/site-packages is in that list. If not, append it

os.sys.path.append('/usr/local/lib/python2.7/site-packages') and try to load it. If that still doesn't work, try re-installing the module, because it seems there is an issue there.

1. Identify the location where Python is importing its libraries from

   $ python
   Python 2.7.15+ (default, Aug 31 2018, 11:56:52)
   [GCC 8.2.0] on linux2
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import os
   >>> print os.sys.path
   ['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/wx-3.0-gtk3']
   >>>
   $
   

   2. Identify the location of scapy on you box

   $ which scapy
   /usr/bin/scapy
   $
   

   3. You will no longer get the import error

   $ python
   Python 2.7.15+ (default, Aug 31 2018, 11:56:52)
   [GCC 8.2.0] on linux2
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import os
   >>> os.sys.path.append('/usr/bin/')
   >>> from scapy.all import *

If you are using termux maybe you shoud try this:

pip2 install scapy.
