在Windows 7上安装Scrapy-Python和Easy_install

Question

我正在尝试在Windows 7上安装Scrapy。我正在按照以下说明进行操作：

http://doc.scrapy.org/en/0.24/intro/install.html#intro-
install

我已按照本教程https://adesquared.wordpress.com/2013/07/07/setting-up-python-and-
easy_install-on-
windows-7/
下载并安装了适用于Windows的python-2.7.5.msi。，并且如上所述设置环境变量，但是当我尝试在命令提示符下运行python时，出现此错误：

Microsoft Windows [Version 6.1.7600]

C:\>python
‘python’ is not recognized as an internal or external command,
operable program or batch file.

C:\> python ez_setup.py install

你能帮我解决这个问题吗？

Answer 1

ur是python2语法，您正试图安装一个不兼容的软件包，该软件包用于python2而非python3：

_ajax_crawlable_re = re.compile(ur'<meta\s+name=["\']fragment["\']\s+content=["\']!["\']/?>')
                                 ^^ python2 syntax

默认情况下，python3.4还安装了pip
