the input device is not a TTY. If you are using mintty, try prefixing the comma

windows上执行Docker命令，如：

docker exec -it mysql mysql -uroot -p

就会报错：

 the input device is not a TTY. If you are using mintty, try prefixing the command with 'winpty'

需要在执行Docker命令之前，加 winpty，如：

winpty docker exec -it mysql mysql -uroot -p
