  • 0

I’m trying to deploy a simple app, getting started on Heroku/Cedar but it’s imposible in Windows. Getting next error running ‘foreman start’, and also an error doing ‘bundle install’ and I’m stuck with it. In this post they conclude it’s imposible to work with it in windows, but I know people are working in Windows with the current version, so I don’t know how they do it, if they use another gem instead of ‘foreman’. I’m really new into this, so I can’t manage a solution/workaround.

c:\workspace\rorprueba>ruby -v
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]

c:\workspace\rorprueba>gem list | grep heroku
heroku (2.18.1)

c:\workspace\rorprueba>foreman start

    Windows doesn’t have true pseudoterminals, so the PTY library isn’t available. Foreman requires this, and thus cannot work on Windows, it seems.

    There seems to be someone working on a C# re-implementation of Foreman, you could have a look at it here.

    Source: https://github.com/ddollar/foreman/issues/41

    You could also have a look in the file Procfile. This is what foreman uses to see what processes to start up. You could execute that command yourself instead of using foreman.
