不确定你是否已经解决了。我今天遇到了这个问题，这就是我解决它的方法，直接获取lxml二进制文件：http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

和pip install Scrapy以某种方式忽略了你安装它并再次尝试构建的事实，因此它将失败。但是，在运行pip install的目录中，将有一个'build'目录，在那里找到'Scrapy \ setup.py'。

现在找到文件的底部：

setup_args ['install_requires'] = ...

并删除lxml和pyopenssl（如果你正在使用windows，你很可能需要直接安装二进制文件，可以在这里找到顺便说一下：http://slproweb.com/products/Win32OpenSSL.html）

从同一目录再次运行pip install Scrapy，你应该好好去。

我遇到了同样的问题（Windows 10，Python 2.7.12），这对我有用。我使用“pip install scrapy”而不是“easy_install”。如果你没有为2.7安装pip，这里是official documentation。如果仍然无效，您可以尝试按照manual installation directions

进行操作
