Windows7 Python-3.6 安裝PyCrypto(pycrypto 2.6.1)出現錯誤以及解決方法

今天準備在Windows系統上基於python3.6安裝一個pycrypto 2.6.1模塊，很不幸的報了一堆錯誤，如下所示：

running install

running build

running build_py

running build_ext

經過一番百度和Google以及嘗試終於成功安裝pycrypto 2.6.1，具體解決方法如下：

1. 設置Microsoft Visual Studio 14.0的環境變量，如圖：

2. 打開cmd，執行如下命令：set CL=/FI"%VCINSTALLDIR%\\INCLUDE\\stdint.h" %CL%
   

3. 重新安裝pycrypto 2.6.1

   通過cmd進入pycrypto 2.6.1目錄，執行python setup.py install

4. 結果如下所示：

   成功安裝pycrypto 2.6.1。。。。。。。
