ruby-debug with Pow — breakpoints never hit

Question

I\'m trying to use ruby-debug with Pow. Rails 3 app.

I have done everything here: https://gist.github.com/1098830

I\'ve restarted the server and machine several

Answer 1

This happens because Pow runs two worker processes as default, and rdebug only connects to one of them. If the other process serves the request, then no dice. The solution is to force Pow to run a single worker process, as follows:

1. Edit ~/.powconfig to contain export POW_WORKERS=1
2. Restart Pow itself by killing the Pow process

You should now hit your breakpoint on every request.
