Python 2.7 Can'；t为Python 2.7安装Scrapy

我正在尝试根据安装Scrapy for Python 2.7。我已经安装了pip，但当我尝试从Windows 8命令提示符运行以下命令时：

pip install Scrapy

它似乎安装不正确，这里是pip.log的结尾

  warnings.warn(msg)

我以前安装了StudioToo工具，所以我不确定日志文件到底指什么？

我可能查看了相关错误的副本，但它们似乎涉及VisualStudio，我不使用。错误是因为Scrapy的一些依赖项需要C++编译器。您可以一个接一个地修复依赖项，也可以从可执行文件安装scrapy。这个答案中链接了scrapy可执行文件-谢谢Shaktiman。我终于成功了，我没有意识到，Sury需要一个C++编译器。
