解决办法：

http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted 下载twisted对应版本的whl文件（如我的Twisted-18.4.0-cp36-cp36m-win_amd64.whl），cp后面是python版本，amd64代表64位，运行命令：

pip install  C:\Users\xjd_0\Downloads\Twisted-18.4.0-cp36-cp36m-win_amd64.whl

其中install后面为下载的whl文件的完整路径名

安装完成后，再次运行：

pip install scrapy

即可成功。
