我在 Ubuntu 上使用 ruby 1.9.2 和 rake 0.9.2.2。
当我想
rake db:migrate
我收到以下错误消息
rake aborted!

Tasks: TOP => db:migrate => environment
我可以通过注释掉我的语言环境文件的第 89 行来解决这个问题：
open_tasks: %{total} (%{count} offen)
但是每次我想迁移数据库时都这样做很烦人......
问题似乎是第一个百分号前面的空白字符。如果我将线路更改为
open_tasks: (%{total} (%{count} offen)
我可以在不堕胎的情况下迁移。
如何避免此解析器错误？
谢谢克里斯蒂安
