How to match between RAils 4.2.4 and DB?

Question

Ruby on Rails

I have rails 4.2.4
and this is the error I get with rake db:test:clone

when fixing it manually rake db:migrate RAILS_ENV =test the same
when using ActiveRecord :: Migrate .maintain_test_schema! error remains

Answer 1

1. Environment variables are assigned without spaces before and after equals.
2. Specify environment variables always before executing the command, not after. Because if you do it after, then the command may start to work incorrectly, since the variable gets inside the script and god knows how it processes it. Based on your output, rake thinks it's a command.
