apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev
./configure --prefix=/usr/local/Python-3.6/
or
./configure --enable-optimizations --prefix=/usr/local/Python-3.6/ --使用了--enable-optimizations安装出现失败，具体原因不知道
make --编译
make install --编译安装
mv /usr/bin/python /usr/bin/python_bk
