在Windows 10 python 2.7（64位）上安装pypcap

Question

我正在尝试从https://github.com/dugsong/pypcap/blob/master/INSTALL#L75安装pypcap

我试图在Windows10-64位和Python2.7.1164位上安装它。我下载了源代码并将其移动到c:\pypcap。下载并安装了pyrex。它将wpdpack文件放入c:\wpdpack中，就像安装页面所说的那样。创建了配置文件并更改了生成文件。

我还用basic包和g++包从他们的网站安装了mingw。

我试着做：

C:\pypcap> set PATH=%PATH%;c:\MinGW\bin;c:\Python27
C:\pypcap> mingw32-make

在这里它失败了，它得到以下错误：

In file included from C:\Python27\include/Python.h:8:0,
                 from pcap.c:4:
C:\Python27\include/pyconfig.h:68:16: fatal error: io.h: No such file or directory
 #include <io.h>

所以我没有这个io.h文件。我该怎么做才能使它编译并使用pypcap？

在我尝试之前

C:\pypcap>pip install pypcap
Collecting pypcap
  Using cached pypcap-1.1.4.tar.gz
    Complete output from command python setup.py egg_info:
    pcap.h not found

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\USER\appdata\local\temp\pip-build-fvgkhs\pypcap\

在那之后，我尝试使用轮子下载，但也失败了。

提前谢谢你的帮助

更改了答案

• 下载https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download。

• 运行它。

• 选择：

  • mingw32基

  • 明W32-gcc-g++

• 选择菜单“安装”=>；“应用更改”

现在，您有了一个全功能的MinGW GCC编译器，其中包括头文件。

io.h应该位于C:\MinGW\include。

更新

我已经成功地使用Python 2.7.11（在Wine下，因为我不运行Windows，但应该是相同的）按照您在问题中描述的过程编译了它。

我必须做的一件事是修改pypcap中的setup.py部分，因为它没有设置到pcap include的正确路径。

如果你到了那里请告诉我。

希望有帮助。

更改为setup.py

将函数_pcap_config替换为此修改版本：

def _pcap_config(self, dirs=[ None ]):
    cfg = {}
    if not dirs[0]:
        dirs = [ '/usr', sys.prefix ] + glob.glob('/opt/libpcap*') + \
               glob.glob('../libpcap*') + glob.glob('../wpdpack*')
    for d in dirs:
        for sd in ('include/pcap', 'include', ''):
            if os.path.exists(os.path.join(d, sd, 'pcap.h')):
                cfg.setdefault('include_dirs', []).append(os.path.join(d, sd))
    for d in dirs:
        for sd in ('include/pcap', 'include', ''):
            for sd in ('lib', 'lib64', ''):
                for lib in (('pcap', 'libpcap.a'),
                            ('pcap', 'libpcap.so'),
                            ('pcap', 'libpcap.dylib'),
                            ('wpcap', 'wpcap.lib')):
                    if os.path.exists(os.path.join(d, sd, lib[1])):
                        cfg['library_dirs'] = [ os.path.join(d, sd) ]
                        cfg['libraries'] = [ lib[0] ]
                        if lib[0] == 'wpcap':
                            cfg['libraries'].append('iphlpapi')
                            cfg['extra_compile_args'] = \
                                [ '-DWIN32', '-DWPCAP' ]
                        print 'found', cfg
                        self._write_config_h(cfg)
                        return cfg
    raise Exception("couldn't find pcap build or installation directory")

它基本上只是将包含pcap.h的所有路径添加到include中。

使用MinGW（32位），您需要32位Python安装。对于64位Python，您需要安装MinGW (64-bit)。

因此，您可以安装32位Python，也可以安装64位MinGW。

我们已经接近了，你会成功的：）

Answer 2

1. 解压缩WinPcap Developer pack，这样就有了C:\WpdPack\Include和C:\WpdPack\Lib

2. 解压缩pypcap source，这样就有了C:\pypcap-1.1.4\setup.py

3. 安装Microsoft Visual C++ Compiler for Python 2.7

4. 从
   启动Python27位的相关命令提示符 Start -> Programs -> Microsoft Visual C++ Compiler Package for Python 2.7

5. 使用以下命令从该命令提示符安装/生成pypcap：

    set INCLUDE=%INCLUDE%;c:\WpdPack\Include
    set LIB=%LIB%;c:\WpdPack\Lib
    pushd C:\pypcap-1.1.4
    python setup.py install
