推荐答案
不确定你是否已经解决了.我今天遇到了这个问题，这是我解决它的方法，直接获取 lxml 二进制文件:http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
Not sure if you have solved it already. I ran into this problem today and here is how I solved it, grab the lxml binary directly: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
和 pip install Scrapy 以某种方式忽略了您已安装并尝试再次构建的事实，因此它会失败.但是，在运行 pip install 的目录中会有一个build"目录，在那里找到Scrapy\setup.py".
and pip install Scrapy somehow ignores the fact that you have it installed and tries to build again, so it will fail. However, in the directory where you run pip install there will be a 'build' directory, find 'Scrapy\setup.py' there.
现在在文件底部找到:
setup_args['install_requires'] = ...
setup_args['install_requires'] = ...
并删除 lxml 和 pyopenssl(如果您在 Windows 上工作，您很可能需要直接安装二进制文件，顺便说一句，可以在这里找到:http://slproweb.com/products/Win32OpenSSL.html)
and remove lxml and pyopenssl (you will most likely need to install the binary directly if you are working on windows, which btw can be found here: http://slproweb.com/products/Win32OpenSSL.html)
从同一目录再次运行 pip install Scrapy，你应该很高兴.
run pip install Scrapy again from the same directory and you should be good to go.
