Question

当我运行rake db：seed时，我收到一个错误，我假设可能与日期对象有关，这些对象是我在seeds.rb中创建的模型上的属性。如果这是原因，有办法解决吗？这是错误输出：

rake aborted!

我已经看到了与Heroku相关的这个错误，但没有关于它在本地机器上发生的事情。大多数答案都与切换到Ruby 1.9.2有关，然而，这会引发错误，因为我在应用程序中使用的几个宝石需要Ruby 1.9.3或更高版本。非常感谢任何帮助，谢谢！

PostgreSQL没有将Date识别为有效输入。通过更改以下内容：

Date.new(2014,1,17)

为：

Date.parse("2014-1-17")

我能够获得填充数据库的种子。

无法执行rake db：seed，接收PG :: InvalidTimeZoneDisplacementValue：ERROR
