[RUBY] Where I got stuck in today's "rails tutorial" (2020/10/08)

Where it gets stuck

2.1 Application planning

-Event: The heroku command is not recognized by $ heroku create -Solution: In toy_app, I started over from the heroku installation of "1.5.1 Heroku setup". -Note: Is it necessary to install for each app? Confirmation required

Today's summary

･ Progress: Chapter 2 2.1.1 ~ 2.2.1 Completed

-Impression: When you type a command to terminal, you should always be aware that the current directory is important.
