没有名为pcapy pyinstaller的模块

Question

This is my first time using pyinstaller and after I build my executable and try to run my executable I get ImportError: No module named pcapy . Can someone tell me why the module might be missing? Not sure if it helps but my script is 1 file and here are all my imports:

from tornado.websocket import WebSocketHandler
from tornado.httpserver import HTTPServer
from tornado.web import Application
from tornado.ioloop import IOLoop

import subprocess
import threading
import os

import sys
from scapy.all import *
import logging

I'm running OS X 10.10.5, scapy 2.3.1 and python 2.7.9

Create a file called hook-pcap.py with the following content:

import os
import glob
import itertools

try:
    # PY_EXTENSION_SUFFIXES is unavailable in older versions
    from PyInstaller.hooks.hookutils import PY_EXTENSION_SUFFIXES
except ImportError:
    try:
        from importlib.machinery import EXTENSION_SUFFIXES as PY_EXTENSION_SUFFIXES
    except ImportError:
        import imp
        PY_EXTENSION_SUFFIXES = set([f[0] for f in imp.get_suffixes()
                                     if f[2] == imp.C_EXTENSION])

def hook(mod):
    module_directory = os.path.dirname(mod.__file__)
    bundled = []

    for libname, ext in itertools.product(('pcap', ),
                                          PY_EXTENSION_SUFFIXES):
        bundled.extend(glob.glob(os.path.join(module_directory, libname + ext)))

    for f in bundled:
        name = os.path.join('pcap', os.path.basename(f))
        if hasattr(mod, 'pyinstaller_binaries'):
            mod.pyinstaller_binaries.append((name, f, 'BINARY'))
        else: # mod.pyinstaller_binaries is unavailable in older versions
            mod.binaries.append((name, f, 'BINARY'))

    return mod

Repeat the process with hook-dnet.py :

import os
import glob
import itertools

try:
    # PY_EXTENSION_SUFFIXES is unavailable in older versions
    from PyInstaller.hooks.hookutils import PY_EXTENSION_SUFFIXES
except ImportError:
    try:
        from importlib.machinery import EXTENSION_SUFFIXES as PY_EXTENSION_SUFFIXES
    except ImportError:
        import imp
        PY_EXTENSION_SUFFIXES = set([f[0] for f in imp.get_suffixes()
                                     if f[2] == imp.C_EXTENSION])

def hook(mod):
    module_directory = os.path.dirname(mod.__file__)
    bundled = []

    for libname, ext in itertools.product(('dnet', ),
                                          PY_EXTENSION_SUFFIXES):
        bundled.extend(glob.glob(os.path.join(module_directory, libname + ext)))

    for f in bundled:
        name = os.path.join('dnet', os.path.basename(f))
        if hasattr(mod, 'pyinstaller_binaries'):
            mod.pyinstaller_binaries.append((name, f, 'BINARY'))
        else: # mod.pyinstaller_binaries is unavailable in older versions
            mod.binaries.append((name, f, 'BINARY'))

    return mod

When building, specify pcap and dnet as hidden imports and supply the path to the directory in which you placed the hook files as a value to the --additional-hooks-dir argument, as follows:

--hidden-import=pcap --hidden-import=dnet --additional-hooks-dir=<path_to_directory_of_hook_files>

Answer 2

I also encounter this problem, when I want to use pyinstaller to convert a python script, which use pcapy module directly, to a executable. And below is my solution.

Enter the python module directory, where is Lib/site-packages in Windows. And I found that the pcapy module existed as a single file, named 'pcapy-0.10.9-py2.7-win-amd64.egg'. I thought it may be some compress technique, and pyinstaller was unable to analysis this compressed file in that time. So I extract the 'pcapy-0.10.9-py2.7-win-amd64.egg', and delete the original 'pcapy-0.10.9-py2.7-win-amd64.egg' file, rename the extracted directory to 'pcapy-0.10.9-py2.7-win-amd64.egg'.

Then, I converted the script again, and this time, the executable worked right, no any import error.
