python setup.py egg_info_Pip安装错误-命令python setup.py egg_info失败，错误代码为1

我刚刚在一个Windows7(32位)框中安装了Python2.7.5。

当试图通过Windows控制台安装Scrapy模块时，出现以下错误：Command python setup.py egg_info failed with error code 1 in c:\users\compaq\app

data\local\temp\pip_build_COMPAQ\pyOpenSSL

Storing debug log for failure in C:\Users\COMPAQ\pip\pip.log

我已经阅读了关于这个的其他线程，建议重新安装或更新安装工具。我已经尝试过了(有最新的安装工具)，但是仍然存在安装错误。

以下是完整的安装脚本和失败：C:\Windows\system32>pip install scrapy
