Invalid JSON RPC response

[redreceipt]

Trying to go through the tutorial, truffle migrate is throwing an error trying to connect to the "network" but I don't think the context of this error has been covered error, have no idea how to move forward.

dbank % truffle migrate                            (starter_kit) dbank ?*

Figured it out. I missed the "Install and open Ganache" step. Needed a running blockchain to deploy too.

Hi Greg,

I am following the tutorial but I ran into an error when I got to the const token = await Token.deployed() step (YouTube timestamp 32:06). I am using VSCode on Ubuntu 20.04 with the following versions:
Truffle v5.2.5 (core: 5.2.5)
Solidity - >=0.6.0 <0.8.0 (solc-js)
Node v10.19.0
Web3.js v1.2.9

I have ganache running and it deployed the contract the first time through with no problems. But now if I try to re-deploy, truffle says there are no changes and nothing has been updated. Please let me know if you have any input on how I can fix this. Thank you for your help and your tutorials.

Hey celsod,

Just do: truffle migrate --reset

Should work

I had this problem after using "truffle migrate --reset"
Invalid JSON RPC response: "Error: connect ECONNREFUSED 127.0.0.1:7545\

turns out I didn't have ganache open, so I opened it, and then used the command "truffle migrate --reset" again and it went through successfully this time...
The little things am I right??
