在win10的环境下安装scrapy，并不能直接按照官网的手册（http://doc.scrapy.org/en/1.0/intro/install.html）一次性安装成功，根据我自己的安装过程中遇到的问题，特意整理了一下安装过程

1.下载安装python2.7.11

https://www.python.org/

2.安装完成之后，把安装路径和脚本路径添加到path中，譬如：C:\Python27\;C:\Python27\Scripts\;

3.安装pywin32，在下面的连接中下载最新版的pywin32

http://sourceforge.net/projects/pywin32/files/pywin32/

我在安装pywin32过程中遇到错误提示：

python version 2.7 required,which was not found in the registry

这是因为注册表不能识别出python2.7，解决方法就是新建一个register.py文件，运行下面的代码

# script to register Python 2.0 or later for use with win32all
# and other extensions that require Python registry settings

            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)

    print "*** You probably have another Python installation!"

    RegisterPy()
