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

windows上執行Docker命令，如：

docker exec -it mysql mysql -uroot -p
複製代碼

就會報錯：

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

須要在執行Docker命令以前，加 winpty，如：

winpty docker exec -it mysql mysql -uroot -p
複製代碼
