在Windows Server 2008安装pyOpenSSL遇到的问题

夏寥寥

Hi，在在Windows Server 2008安装pyOpenSSL遇到一些问题，还请大家帮忙看一下！

Visual Studio 2012安装在E盘；
OpenSSL安装在C盘；


1. 首先下载了格式为.tar.gz的pyOpenSSL文件

下载地址：https://pypi.python.org/pypi/pyOpenSSL

2. 然后在命令行使用python setup.py install进行安装；之后陆续出现了一些错误；大部分都是缺少依赖文件；

3. 之后在安装cryptography.tar.gz提示如下错误：


4. 根据错误提示，说是系统变量没设置好；于是进入到Visual Studio 2012的安装目录下，找到vcvars64.bat并执行来设置环境变量；

但是在执行后，系统没有任何提示，再次执行第3步的操作时，发现还是报之前的错误；



5. 之后又打开vcvars64.bat文件查看，也没看懂什么意思；

错误：build\temp.win-amd64-2.7\Release\_openssl.c(415) fatal error C1083:Cannot open include file (openssl\e_os2.h) no such a file or directory;
解决方法：该错误是由于系统找不到文件openssl\e_os2.h，在系统中设置变量即可；

变量名：include
变量值：C:\OpenSSL1.0\setup\OpenSSL-Win32\include （根据你系统中openssl安装的位置进行调整）

然后重启机器即可；

在安装cryptography时报如下错误：

回复 3# 夏寥寥

该报错的原因是由于：Python（64-bit）和OpenSSL(32-bit)安装的位数不一致, 把OpenSSL替换成64-bit的即可解决该问题；
