问题
I keep getting this error
"Unhandled Rejection (Error): This contract object doesn't have address set yet, please set an address first. " when launching truffle unbox react, and also I don't have truffle.js, only have truffle-config.js

Assuming your metamask extension is enabled, make sure to switch your network to the localhost that is running either ganache-cli or truffle.
