上面还省略了很长一段，在此之前我已经安装了openssl-devel, 在此之前有在别地方看到说通过anaconda安装uwsgi，因为不想去再安装anaconda就没有尝试这个方式: https://github.com/unbit/uwsgi/issues/1516
github上的解决方案2:https://github.com/unbit/uwsgi/issues/1516
我的问题以及解决方法：
卸载openssl-devel
我的问题是之前通过yum安装了openssl-devel，但是使用pip命令时还是出现ssl报错，因为pip命令用不了，所以又通过源码编译安装了新的OpenSSL(OpenSSL 1.1.1a),但是忘记卸载了yum安装的OpenSSL(openssl-devel-1.0.2),估计是这两个冲突了，卸载yum安装的OpenSSL后就好了，白忙活了好一阵
卸载OpenSSL yum remove openssl-devel
查看OpenSSL版本 openssl version
