#  建立新目录#  sudo mkdir /usr/local/python3  # 下载安装包#  wget --no-check-certificate https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz #  解压安装包#  tar xzvf Python-3.8.2.tgz #  cd Python-3.8.2 #  编译安装#  sudo ./configure --prefix=/usr/local/python3

#  sudo make 

#  sudo make install

#  删除默认Python软连接#  rm /usr/bin/python       #  创建软链接                               # sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python

4.验证python安装

#  python -V

5.安装pip

#  /usr/bin/python -m pip install --upgrade pip
