我相信这是在升级到Ruby 2.0.0之后发生的，然后我重新设置了罗盘手表所需的宝石。我还安装了Ruby 1.9.1并安装了罗盘手表的宝石并得到了同样的错误。我试图更改文件.listen_test的权限，但它不存在。
这是--trace：

EDIT 通过安装旧版指南针（0.12.2）
，我得到罗盘表答案 0 :(得分：4)
我发现它适用于：
sudo compass watch
我不确定为什么现在我需要sudo。
答案 1 :(得分：1)
您拥有其中一个宝石的旧版本。我猜它是'听'
有人遇到了同样的问题。

编辑：实际上这可能是指南针问题。做了一些局部变化，超越了错误。 Pull请求已发布待审核。我不做红宝石，但希望它是解决问题的开始。 https://github.com/chriseppstein/compass/pull/1522
