sudo: no tty present and no askpass program specified
===

I tried [jake](https://github.com/mde/jake) together with [launch](https://github.com/bengourley/launch) a little but when I want to deploy my node.js app I get this during the process:
 
    $ ssh mydomain.com sudo stop site.WebApp-production && sudo start site.WebApp-production
    sudo: no tty present and no askpass program specified
    
    ✘  Failed to restart site
    
    jake aborted.
    Error
      at fail (/usr/local/lib/node_modules/jake/lib/api.js:235:13)

      at ChildProcess.EventEmitter.emit (events.js:91:17)
      at Process._handle.onexit (child_process.js:674:10)

Do you know how to get rid of this? I'm using Debian 6 on my remote machine.

Thanks
