1.安装编译环境
sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev
2.下载Python-3.7.2.tgz
3.解压
tar -xvzf Python-3.7.2.tgz
4.进入目录
cd Python-3.7.2/
5.配置编译
./configure --prefix=/usr/bin/python3.7
6.编译及安装
sudo make && sudo make install
6。设置python3.7.2的软链接
sudo rm /usr/bin/python3
sudo ln -s /usr/bin/python3.7/bin/python3.7 /usr/bin/python3
7.测试
现在输入python3调用的就不是系统自带的python3.5了，而是刚刚安装好的python3.7
8.设置pip3软连接
rm -rf /usr/bin/pip3
sudo ln -s /usr/bin/python3.7/bin/pip3 /usr/bin/pip3
【pip3报错问题及解决】
subprocess.CalledProcessError: Command ‘(‘lsb_release’, ‘-a’)’ returned non-zero exit status 1.
解决方法
find / -name lsb_release
rm -rf /usr/bin/lsb_release
