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

• I am on the latest Hyper.app v2.0.0
• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: Win10
• Hyper.app version: v2.0.0
• Link of a Gist with the contents of your .hyper.js:
• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere):
• The issue is reproducible in vanilla Hyper.app:

The issue can be simply reproduced by the following command

$ docker.exe run -it --rm ubuntu:14.04 /bin/bash

Just add ‘winpty’ in start of your cmd ,Try below: $ winpty docker.exe run -it --rm ubuntu:14.04 /bin/bash

To anyone potentially having a similar issue with docker, you may not need winpty.

I followed this guide to install docker on WSL rather than passing through to the windows.exe: https://medium.com/@sebagomez/installing-the-docker-client-on-ubuntus-windows-subsystem-for-linux-612b392a44c4

Then I changed my shellArgs in .hyper.js from

 shellArgs: ['--login', '-i', '/c wsl'],

to

shellArgs: ['--login'],

Seems to work fine now.
