Question

我正在尝试在Windows 7上安装HoneyProxy。我已经安装了Python 2.7和pip。它说，

安装所有依赖项：pip install pyOpenSSL pyasn1 Twisted   高速公路

Windows用户：安装pyOpenSSL和Twisted的二进制文件   手动

听起来像cffi或加密libs失败，我不知道哪一个。 OpenSLL和Twisted呢？

编辑：最后，我必须安装

OpenSSL for Windows
pywin32
卸载高速公路并安装高速公路== 0.6.5 （pip install Autobahn==0.6.5）

根据该堆栈，Twisted正在尝试初始化其TCP层，而OpenSSL层又调用cffi，最终调用cffi代码，是Python和C代码之间的桥接接口。

它正在尝试加载 C：\ Python27 \ lib \ site-packages \ cryptography \ _Cryptography_cffi_444d7397xa22f8491.pyd 文件（本质上是一个支持Python的DLL）并且由于错误而无法加载这是陈述。（看起来它没有插入错误字符串中的一个占位符，这是不幸的，因为这可能提供了额外的信息 - 除此之外，消息只是操作系统无法加载文件，这不是很多的诊断，因为这可能由于许多不同的原因而发生。）

首先要检查的是该文件是否确实存在于您的计算机上。如果没有，Windows Event Log的安装可能无法正常运行。如果确实存在，则无法加载它。 {{1}} - 在其中一个视图中 - 可能会更清楚地说明为什么Windows无法加载pyd / DLL。

这可能是32位与64位的问题。看这个FAQ： https://cryptography.io/en/latest/faq/#when-i-try-to-use-cryptography-on-windows-i-get-a-cffi-ffiplatform-verificationerror

我建议尝试安装64位版本（假设你使用的是Win64）。
