Question

I followed this YY video: https://youtu.be/ZB3GLtQvgME?t=2003 but cannot 'chainlink node start'

Running 'chainlink help' is fine. Installation is Ok. Everything before the video checks out.

Need help with 'chainlink node start' Error:

Thank you!

This is the .env

This is what happened if I use Docker: failed to open db: failed to connect to host=localhost user=root database=kovan_demo: dial error (dial tcp [::1]:5432: connect: cannot assign requested address)
