我现在正在使用scrapy几个月。我一直在几台机器上使用它，从来没有遇到过麻烦。我在Windows xp和7上使用它，我也在arch linux上使用它，从来没有遇到过安装问题。差不多只是pip install scrapy并完成了。
现在我正在尝试在使用CentOS的生产服务器上进行设置。由于CentOS默认使用python2.4，我首先进行了python2.7的并行安装。此外，我为python 2.7安装了virtualenv，在那一刻，一切看起来都不会出错，我的环境很干净，并且有了我的点子。
但是当我尝试pip install scrapy时，它给了一个错误。

以下是pip日志文件中保存的错误。

如果有人知道它可能是什么，或者有这个问题，请帮忙。
