When I first load my Dapp with testrpc the functionality doesn't work until I use the command truffle migrate --reset

Any ideas why?

  • When you start testrpc, it's a whole new blockchain (simulation) so previous migrations are absent. Truffle isn't aware of that, so --reset is part of the routine. One possible reason for it. – Rob Hitchens - B9lab Feb 4 '17 at 22:01
  • Ok so it's normal to have to reset the migrations then? – ethereal Feb 6 '17 at 18:48
  • Its' normal for me. :-) – Rob Hitchens - B9lab Feb 6 '17 at 18:57

This is because truffle remembers previous migrations you made but you are on a new test network. You can see registered contract addresses by running truffle networks.

You can delete these informations by running truffle networks --clean before truffle migrate.
