Hi @Aufree I didn't know launchy was used by heroku :-).

Can you do me a favor and run export LAUNCHY_DEBUG=true heroku open <rest of command line if there was any> and post the output here?

Aufree commented Mar 2, 2014

Hi @copiousfreetime ,I think,Maybe i not installed any browser at my computer,Because i worked on my virtualbox...


copiousfreetime commented Mar 5, 2014

@Aufree That would do it, launching a browser from within the virtual box would do nothing if there was no browser installed. Also, you will need to have a window manager installed, and be viewing the graphical interface to get any of the normal browsers to do anything visible.

I'm going to close this issue for now. Please reopen if you have problems.

For others who also get this problem when working on a virtualbox (my case is on c9 with ec2 machine), just run: sudo apt-get install iceweasel. That will install browsers to the box and fix this error
