[Heroku] No app specified. 😅 how to omit -a, --a option

🤔 Situation

$ heroku apps:info
 ▸    No app specified.
 ▸    USAGE: heroku info my-app

👍 Solution

1. Check your git remote

$ git remote -v
origin  [e-mail]:n350071/my-app.git (fetch)
origin  [e-mail]:n350071/my-app.git (push)

2. set the git remote to heroku

Then, Heroku will automatically detect your app when you're in the git managed directory.

$ heroku git:remote --app my-app-prototype
set git remote heroku to https://git.heroku.com/my-app-prototype.git

$ git remote -v
heroku  https://git.heroku.com/my-app-prototype.git (fetch)
heroku  https://git.heroku.com/my-app-prototype.git (push)
origin  [e-mail]:n350071/my-app.git (fetch)
origin  [e-mail]:n350071/my-app.git (push)

🦄 Solved
