终于到了激动人心的时候了！安装了那么多小部件之后终于轮到主角登场。
直接在cmd中输入easy_install scrapy回车即可。
出现如下错误

error: Setup script exited with error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from

解决办法的前提是，系统中必须安装了vs的相关版本。

For Windows installations:

While running setup.py for package installations, Python 2.7 searches for an installed Visual Studio 2008. You can trick Python to use a newer Visual Studio by setting the correct path in VS90COMNTOOLS environment variable before calling setup.py.

If you have Visual Studio 2010 installed, execute

SET VS90COMNTOOLS=%VS100COMNTOOLS%

or with Visual Studio 2012 installed (Visual Studio Version 11)

SET VS90COMNTOOLS=%VS110COMNTOOLS%

or with Visual Studio 2013 installed (Visual Studio Version 12)

SET VS90COMNTOOLS=%VS120COMNTOOLS%
