heroku db：pull无法连接数据库NoMethodError

When I run heroku db:pull I get a NoMethodError. Fervent googling has failed to provide a solution.

当我运行heroku db:pull我得到一个NoMethodError。热切的谷歌搜索未能提供解决方案。

rails_app[master*]/
↪ heroku db:pull --remote [app] --confirm [app]
Loaded Taps v0.3.24
Auto-detected local database: postgres://127.0.0.1/[db name]?encoding=utf8
Warning: Data in the database 'postgres://127.0.0.1/[db name]?encoding=utf8' will be overwritten and will not be recoverable.
Failed to connect to database:
  NoMethodError -> undefined method `close' for nil:NilClass

The result is the same when I supply the database name as postgres://localhost/app_development

当我提供数据库名称为postgres:// localhost / app_development时,结果是一样的

I have taps, pg, sequel installed:

我有水龙头,pg,续集安装:

rails_app[master*]/
↪ gem list --local | grep -E taps\|pg\|sequel
pg (0.15.1, 0.15.0, 0.14.1)
sequel (3.46.0, 3.20.0)
taps (0.3.24)

And just in case, my rails config/database.yml

为了以防万一,我的rails config / database.yml

development: &default
  adapter: postgresql
  database: app_development
  encoding: utf8
  min_messages: warning
  pool: 5
  timeout: 5000

test:
  <<: *default
  database: app_test

I'm on Rails 3.2.13.

我在Rails 3.2.13上。

Has anyone run into this and come up with a solution?

有没有人碰到这个并想出一个解决方案?
