database - Heroku pg :push command missing

Question

我尝试通过执行heroku db:push将我的数据库推送到heroku，这给了我以下错误:

!    db:push and db:pull have been removed and replaced with pg:push and pg:pull.
!    For more information, please see:
!      devcenter.heroku.com/articles/heroku-postgresql#pg-push-and-pg-pull

所以我尝试了 heroku pg:push 这给了我这个错误:

!    `pg:push` is not a heroku command.
!    Perhaps you meant `db:push` or `pg:ps`.

和 heroku help pg 给出

pg:credentials DATABASE  #  Display the DATABASE credentials.
pg:info [DATABASE]       #  Display database information
pg:promote DATABASE      #  Sets DATABASE as your DATABASE_URL
pg:psql [DATABASE]       #  Open a psql shell to the database
pg:reset DATABASE        #  Delete all data in DATABASE
pg:unfollow REPLICA      #  stop a replica from following and make it a read/write database
pg:wait [DATABASE]       #  monitor database creation, exit when complete

我的应用程序位于 cedar 堆栈上，这是我正在使用的完整命令:

heroku pg:push my_local_name HEROKU_POSTGRESQL_CHARCOAL --app my_app_name

还尝试了添加 pgbackups 的建议，但我仍然遇到相同的错误。

我发现，我正在使用heroku gem(在ruby 1.9上)，当我去查看1.9和2.0上的gem是否有区别时，我看到了弃用通知。现在，这可以按照 heroku-toolbelt 的预期工作。安装并移除 gem 。
