我现在正在使用scrapy几个月。我一直在这台机器上使用它，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，并且从未遇到过安装问题。几乎它只是点安装scrapy并完成。安装scrapy（openSSL）
现在我正试图在使用CentOS的生产服务器上进行设置。由于默认情况下，CentOS具有python2.4，所以我并行安装了python2.7。另外我为python 2.7安装了virtualenv，在这一点上，一切都看起来像不会出错，我有我的清洁环境，并有我的点子。
但是当我尝试pip安装scrapy时，它给了一个错误。
OpenSSL/ssl/connection.c: In function 'ssl_Connection_set_context':
OpenSSL/ssl/connection.c:289: warning: implicit declaration of function'SSL_set_SSL_CTX'
OpenSSL/ssl/connection.c: In function 'ssl_Connection_get_servername':

而这下面是保存在pip日志文件中的错误。
运行setup.py egg_info用于包装pyOpenSSL

如果有人有一个想法是什么莫非，还是有这个问题，请帮助。
