centos7安装python3.7.2后,运行
pip3 install tornado
会报错
[root@localhost ~]# pip3 install tornado
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

解决方法:
在./configure过程中,如果没有加上–with-ssl参数时,默认安装的软件涉及到ssl的功能不可用,
刚好pip3过程需要ssl模块,而由于没有指定,所以该功能不可用。

查看openssl安装包,发现缺少openssl-devel包
[root@localhost ~]# rpm -aq|grep openssl
openssl-0.9.8e-.el5
openssl-0.9.8e-.el5
[root@localhost ~]# -
yum安装openssl-devel
[root@localhost ~]# yum install openssl-devel -y
查看安装结果
[root@localhost ~]# rpm -aq|grep openssl
openssl-0.9.8e-.el5_9.
openssl-0.9.8e-.el5_9.
openssl-devel-0.9.8e-.el5_9.
openssl-devel-0.9.8e-.el5_9. -
重新对python3.7.2进行编译安装,用以下过程来实现编译安装
cd Python-3.7.2
./configure --with-ssl
make
sudo make install
