    i'm having the same issue when im not connected to the internet. running local testrpc. There has been some discussion on gitter that starting testrpc in the same dir as you migrate helps however it didnt make any difference for me. have you made any progress?

  • I usually have this error when testRPC dies in the background. Have you checked the console output of testrpc? What's your testrpc version? I've encountered more testrpc crashes with newer versions but the latest 4.0.1 is fairly stable again

  • I am having the same problem, did anyone get the solution? I have tried using ganache and testrpc both. But, neither worked. Also, I tried starting testrpc in my current project directory but it too didn't do any good. I am questioning my life right now :D

As suggested by @Rob, running testrpc from the same folder in which truffle console is run solved the issue in my case
