pip：理解缺失库的转储

Question

我正在尝试在Windows 7上安装HoneyProxy。我已经安装了Python 2.7和pip。它提示我：

安装所有依赖项：使用命令 pip install pyOpenSSL pyasn1 Twisted Autobahn

Windows用户：需要手动安装pyOpenSSL和Twisted的二进制文件。

这是我pip的安装列表：

astropy (0.3.1)
autobahn (0.8.8)
beautifulsoup4 (4.3.2)
cffi (0.8.2)
cryptography (0.4)
httplib2 (0.8)
matplotlib (1.3.1)
numpy (1.8.1)
oauth2 (1.5.211)
oauthlib (0.6.0)
pip (1.5.4)
pyasn1 (0.1.7)
pycparser (2.10)
pyopenssl (0.14)
pyparsing (2.0.1)
python-dateutil (2.2)
pytz (2014.2)
requests (2.2.1)
requests-oauthlib (0.4.0)
setuptools (3.4.4)
simplejson (3.3.2)
six (1.6.1)
Twisted (14.0.0)
TwitterAPI (2.1.13)
urwid (1.2.1)
wikipedia (1.1dev)
wsgiref (0.1.2)
zope.interface (4.1.1)

我已经手动安装了pyOpenSSL和Twisted。当我尝试运行python honeyproxy.py时，出现了以下信息：

听起来像是cffi或cryptography库出问题了，我不确定是哪一个。OpenSSL和Twisted也有问题吗？

更新：最后，我不得不安装：

Windows版OpenSSL
pywin32
卸载Autobahn并安装Autobahn==0.6.5（使用命令pip install Autobahn==0.6.5）

openssl pyopenssl twisted pip dependency management cffi windows installation autobahn
