ubuntu Python 升级

安装时ubuntu提示：

  

   

    

     

    
    

     

      DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one 
     
    
   

    

     

    
    

     

      supporting it. Please upgrade your Python as Python 3.4 won't be maintained after March 
     
    
   

    

     

    
    

     

      2019 (cf PEP 429).
     
    
   

    

     

    
    

     

      
     
    
  
 

 所以我们要升级一下版本：

  

   

    

     

    
    

     

      wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
     
    
   

    

     

    
    

     

      xz -d Python-3.7.3.tar.xz
     
    
   

    

     

    
    

     

      tar -xvf Python-3.7.3.tar
     
    
   

    

     

    
    

     

      cd Python-3.7.3
     
    
   

    

     

    
    

     

      ./configure --with-ssl
     
    
   

    

     

    
    

     

      sudo make
     
    
   

    

     

    
    

     

      sudo make install
     
    
  
 

如果不成功，安装依赖再试一下：

sudo apt-get install -y zlib*
 

 接着修改软连接

  

   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      sudo rm -rf /usr/bin/python3
     
    
   

    

     

    
    

     

      sudo rm -rf /usr/bin/pip3
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      sudo ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
     
    
   

    

     

    
    

     

      sudo ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3
     
    
  
 

重启即可
