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

并且 pip install Scrapy 以某种方式忽略了你已经安装它并尝试再次构建的事实，所以它会失败。然而，在你运行 pip install 的目录中会有一个'build'目录，在那里找到'Scrapy\setup.py'。

现在在文件底部找到:

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)

从同一目录再次运行 pip install Scrapy，你应该可以开始了。
