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

Question

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：

pip尝试从源代码构建包。因此，您将需要库和VS2008编译器的开发头，所有这些设置都相当痛苦。

从这里下载失败包的预构建二进制文件更容易： http://www.lfd.uci.edu/~gohlke/pythonlibs/

然后重试安装scrapy。
