正常情况下执行：
./configure
make && make install
可以直接安装python，但是在在更新了乌版图后居然报错了！！！
检查了一圈，发现乌版图安装了python3.8，卸载会影响乌版图的组件，
那么只好保留python3.8并安装自己需要的python3.7.8
1.安装gcc和g++
sudo apt-get gcc
sudo apt-get g++
2.重新编译安装Python
(PS:在安装好gcc和g++后编译安装时依然报错解决办法，更新gcc与g++编译正常的可以略过：)
sudo apt-get install build-essential
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev
编译安装Python：
./configure
make && make install
查看python安装是否成功：
python3.7 -V
pip3.7 -V
4.进入Pycharm发现没有python3.7的环境变量，只有python3与python3.8
依次点击：
settings->Project:pythonproject->Python Intepreter->点击设置图标（在右上角）
->add->选择Existing envirnment->填入路径：/usr/local/bin/python3.7->勾选Make available to all projects
5.查看Pycharm右下角显示Python3.7
