在 Python 3.5 环境下安装 scrapy 时报错

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

对症下药吧，到相应地址下载 WordCloud 。比如下载了 wordcloud-1.4.1-cp35-cp35m-win_amd64.whl 。则在终端进入指定位置执行下面语句：

pip install wordcloud-1.4.1-cp35-cp35m-win_amd64.whl
