env: centos7   python3.6.7 (机器为国外的vps,并且安装过openssl)

不知道是我的机器的原因还是什么，网上找的各种方法都不管用，都说加上--with-openssl参数编译，但我实测并不管用，这个参数被忽略掉了，怀疑很多人的博客都是在互相抄作业

[root@centos1 Python-3.6.7]# pip3 install django==1.11.9

网上查找的方法都说是在编译python时加上--with-ssl 或者--with-openssl参数，

但查看了./configure 的参数列表并没有这和项，所以实际中编译时这个参数被忽略，

目前找到的一个可以解决的办法是更换pip源

mkdir ~/.pip
cd .pip
vim pip.conf

[global]
index-url=http://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host=mirrors.aliyun.com

再用pip3 安装就正常了（这里不保证其他人的也管用）。

另外这里安装包时提示需要ssl,怀疑可能是国外vps，pip3源的影响
