The input device is not a tty. if you are using mintty, try prefixing the command with ‘winpty’

When encountering the error message “the input device is not a tty. If you are using mintty, try prefixing the command with ‘winpty’,” it indicates an incompatibility issue with the terminal emulator being used. Specifically, it affects mintty, a terminal for Cygwin and MSYS with a native Windows user interface. The error arises when a command requires a tty (teletypewriter) input, but mintty cannot provide it.

To resolve this issue, the suggested solution is to prefix the command with ‘winpty.’ The ‘winpty’ command is a console interface that allows running Windows command-line applications from within mintty or other compatible terminals. By using ‘winpty,’ it creates an environment that satisfies the tty requirement and removes the error message.

Here is an example of how to use ‘winpty’ to resolve the error:

    $ winpty your_command
  

Replace “your_command” with the actual command that was triggering the error. By adding ‘winpty’ before the command, you can avoid the issue and execute the command successfully in mintty or a similar terminal emulator.
