我在Ubuntu上使用ruby 1.9.2和rake 0.9.2.2。

當我想

rake db:migrate 

我收到以下錯誤消息

rake aborted!

Tasks: TOP => db:migrate => environment 

我可以解決註釋掉我的區域文件的第89行的問題：

open_tasks: %{total} (%{count} offen) 

但是每次我想遷移數據庫時都這麼做很煩人......

問題似乎是第一個百分號前的空白字符。如果我將該行更改爲

open_tasks: (%{total} (%{count} offen) 

我可以在沒有墮胎的情況下遷移。

如何避免此解析器錯誤？

感謝 基督教

Answer 1

您可以使用引號複數值

open_tasks: "%{total} (%{count} offen)"
