【问题描述】：
我试图将我的 rails 项目数据库推送到 heroku 的数据库。
我输入这个
heroku pg:push ReadingList_development DATABASE_URL --app calm-eyrie-9110
（ReadingList_development 是我的本地数据库名称。）
但是，它显示了这个错误
sh: psql: command not found
! Heroku client internal error.

更新
语法应该像
heroku pg:push mylocaldb HEROKU_POSTGRESQL_MAGENTA --app sushi
我不确定mylocaldb 和HEROKU_POSTGRESQL_MAGENTA 应该是什么。当我输入这个
heroku pg:push mylocaldb HEROKU_POSTGRESQL_MAGENTA --app calm-eyrie-9110
返回
Unknown database: HEROKU_POSTGRESQL_MAGENTA. Valid options are: DATABASE_URL
mylocaldb 是否应该与database.yaml 中的名称相同？
这是我的database.yaml 信息
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:
<<: *default
database: ReadingList_development
此外，我输入heroku config:get -a calm-eyrie-9110
返回
! Usage: heroku config:get KEY
! Must specify KEY.

@steveklein ，我阅读了那个答案，但我仍然无法弄清楚，我已经更新了我的问题。

mylocaldb应该是ReadingList_development。我上面引用的帖子提供了确定 Heroku DB 名称的步骤。
