python - 安装scrapy提示openssl版本太老

Question

系统centos5.10
python版本2.7.5
已经安装了scrapy所有依赖包，更新了oenpssl

更新了openssl
[root@iZbp19u6ifs6ey95jlrdqtZ ~]# openssl version
OpenSSL 1.0.1g 7 Apr 2014

这里的版本没变
python -c "import ssl; print ssl.OPENSSL_VERSION"
OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

执行scrapy命令会报错
[root@iZbp19u6ifs6ey95jlrdqtZ ~]# scrapy
