linux環境python3出現pip is configured with locations that require TLS/SSL, however the..不可用的解決方法

首先明確問題出現原因，是因為openssl版本過低或者不存在 so：

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python3.6進行編譯安裝，用一下過程來實現編譯安裝:

cd Python-3.6.4
./configure --with-ssl
make
sudo make install

 

pip install pip -U

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
