Hello @azah, I ran into this very issue today.

After a couple of tries I finally made it ran, first check that you have set the environment variable DB_URL as specified in Readme and second, if you have created an executable file to run micrate, remember to require your database adapter, in my case was postgres.

My bin/micrate file, for whats is worth:

#! /usr/bin/env crystal
require "pg"
require "micrate"

Micrate::Cli.run

Then I was able to run bin/micrate up as usual. Hope it helps 😄

I forgot to add "pg" in my micrate. Thanks!
