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
