已更改答案
现在您拥有一个功能齐全的 MinGW GCC 编译器，包括头文件。
io.h 应位于C:\MinGW\include。
更新
按照您在问题中描述的过程，我现在已经使用 Python 2.7.11（在 Wine 下，因为我不运行 Windows，但它应该是相同的）成功编译它。
我必须做的一件事是修改 pypcap 中的 setup.py 的部分内容，因为它没有设置 pcap 包含的正确路径。
如果/何时到达，请告诉我。
希望对你有帮助。
更改为setup.py
用这个修改后的版本替换函数_pcap_config：
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 ALL 路径添加到包含中。

使用 MinGW（32 位），您需要安装 32 位 Python。使用 64 位 Python，您需要安装 MinGW (64-bit)。
因此，您可以安装 32 位 Python 或安装 64 位 MinGW。
我们现在很接近了，你会成功的 :-)
