python3.7.2 pip 出現locations that require TLS/SSL異常處理方法

 

centos7安裝python3.7.2后，運行

pip3 install tornado

會報錯

[root@localhost ~]# pip3 install tornado

解決方法：

在./configure過程中，如果沒有加上–with-ssl參數時，默認安裝的軟件涉及到ssl的功能不可用，
剛好pip3過程需要ssl模塊，而由於沒有指定，所以該功能不可用。

1. 查看openssl安裝包，發現缺少openssl-devel包 

   [root@localhost ~]# rpm -aq|grep openssl 
   openssl-0.9.8e-20.el5 
   openssl-0.9.8e-20.el5 
   [root@localhost ~]#

    

2. yum安裝openssl-devel 

   [root@localhost ~]# yum install openssl-devel -y 

   
   查看安裝結果 

   [root@localhost ~]# rpm -aq|grep openssl 
   openssl-0.9.8e-26.el5_9.1 
   openssl-0.9.8e-26.el5_9.1 
   openssl-devel-0.9.8e-26.el5_9.1 
   openssl-devel-0.9.8e-26.el5_9.1

    

3. 重新對python3.7.2進行編譯安裝，用以下過程來實現編譯安裝

   cd Python-3.7.2
   ./configure --with-ssl
   make
   sudo make install
