Question

当我运行heroku db:pull时，我得到NoMethodError。热切的谷歌搜索无法提供解决方案。

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

当我提供数据库名称为postgres://localhost/app_development

时，结果相同

我有点击，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)

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

我在Rails 3.2.13。

有没有人碰到这个并提出解决方案？
