一 卸载ubuntu 自带3.5.2
sudo apt-get remove python3.5
sudo apt-get remove --auto-remove python3.5
sudo apt-get purge python3.5
sudo apt-get purge --auto-remove python3.5
二Error: No module named ‘_ctypes’
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
三 Error no module named curses：
1 make之后 发现报错，但是build/lib.linux-86_64 里面已经产生了
_curses_panel.cpython-37m-x86_64-linux-gnu.so 将这个so复制到
/usr/local/lib/python3.7/lib-dynload
2 继续sudo make install 成功
