Push local database data to heroku database

问题

I was trying to push my rails project database to heroku's database.

I type this heroku pg:push ReadingList_development DATABASE_URL --app calm-eyrie-9110

(ReadingList_development is my local database name.)

However, it shows this error

sh: psql: command not found
 !    Heroku client internal error.
 !    Search for help at: https://help.heroku.com

Update

syndax should be like

heroku pg:push mylocaldb HEROKU_POSTGRESQL_MAGENTA --app sushi

I am not sure what mylocaldb and HEROKU_POSTGRESQL_MAGENTA should be. When I type this

heroku pg:push mylocaldb HEROKU_POSTGRESQL_MAGENTA --app calm-eyrie-9110

it return

Unknown database: HEROKU_POSTGRESQL_MAGENTA. Valid options are: DATABASE_URL

Does mylocaldb should be the same name in database.yaml?

here is my database.yaml info

default: &default
  adapter: postgresql
  encoding: unicode
  pool: 5

development:
  <<: *default
  database: ReadingList_development

Furthermore, I type heroku config:get -a calm-eyrie-9110

it return

!    Usage: heroku config:get KEY
!    Must specify KEY.

回答1:

heroku pg:info will either give you the color(HEROKU_POSTGRESQL_MAGENTA) like in the docs, or it will provide something like postgresql-something-12345

Either one of those will suffice in place for the heroku db
