1.安装过程中显示unable to find vcvarsall.bat
这是window环境下安装模块比较常见的问题，这时候你百度的话大部分文章就会告诉你下载vs，python2的话安装vs2010，python3的话安装vs2013
重点！！！！！！！！
不要着急去安装vs，这东西一安装就是好几个小时，在这里我对vs装了卸，卸了装浪费了一天半的时间。
python有个深坑！不同的python版本对应不同的vs版本，如果你跟我一样是python3.6的话应该这里是14，之前就是看到其他的博客，没有查看这里的版本号就装，先是装了vs2010，然后装2013，再卸了装了对应版本号的vs2015，其中vs的版本号对应关系如下：
msvs2005版本号为8.0，对应环境变量VS80COMNTOOLS
msvs2008版本号为9.0，对应环境变量VS90COMNTOOLS
msvs2010版本号为10.0，对应环境变量VS100COMNTOOLS
msvs2012版本号为11.0，对应环境变量VS110COMNTOOLS
msvs2013版本号为12.0，对应环境变量VS120COMNTOOLS
msvs2015版本号为14.0，对应环境变量VS140COMNTOOLS
2.安装对应版本的msvs(Microsoft Visual Studio)
如果是Visual Studio 2015，提供个百度经验上百度网盘给大家
http://pan.baidu.com/s/1eSueWLG
如果不需要用vs进行开发的话，装community免费版就可以了，没必要纠结专业版啥的
安装过程中要注意，建议安装的时候选自定义（截图来自百度经验，因为已经安装了打开之后有点不太一样）
记得勾选VC++2015和Python Tools。Web Deveolper Tools的话最好也勾上吧。
但我的安装过程没这么顺利，泪奔~
安装部分模块失败，然后我重新安装。因为主要的vs2015安装是成功的，所以只勾选
VC++2015
Python Tools
Web Deveolper Tools
这三个模块，500M左右，重新安装就提示全部成功了
很多人说装完之后要改环境变量，
python2：set VS90COMNTOOLS=%VS140COMNTOOLS%
python3：set VS100COMNTOOLS=%VS140COMNTOOLS%
可能python3.6版本高了不需要这样，不过也记录一下给各位看官仅供参考。反正我是不需要改，因为接下来我踩了另一个坑

经过一番百度和Google以及尝试终于成功安装pycrypto 2.6.1，具体解决方法如下：
设置Microsoft Visual Studio 14.0的环境变量，如图：
打开cmd，执行如下命令（划重点，不是有些blog上面的“/”,也不是"\\",我试成功的是"\",另外“-”是需要的，不要问我为啥，我也是试出来的）：set CL=-FI"%VCINSTALLDIR%\include\stdint.h"
重新安装pycrypto 2.6.1
通过cmd进入pycrypto 2.6.1目录，执行python setup.py install
结果如下所示：
成功安装pycrypto 2.6.1。。。。。。。
---------------
从（本例使用的是64位的python3.6 注意：如果python的版本是32位，则使用x86；如果是64位，则使用x64;）
复制一下两个文件
rc.exe
rcdll.dll 到
5.注意是Crypto还是crypto,区分大小写
我这里安装成功之后代码alt+enter自动关联的是
from crypto.Cipher import AES
1
然后代码运行报错，点进去AES里面import的是
from Crypto.Cipher import _AES
可以手动进入python\Lib下，我的路径是
C:\Python36\Lib\site-packages
然后把文件夹crypto改成Crypto。把小写改成大写，刷新下，Finally
