The users table is missing, so

 railsg scaffold user-s --no-style sheets --skip-migration

There is a high probability that you have forgotten to run the , or that you have run it later.
You can use rails destroy to start over, but you are not very familiar with it, so it is recommended that you delete the generated file or start over.
