问题描述
我相信这是在升级到Ruby 2.0.0之后发生的，然后我将指南针手表所需的宝石树脂化了。我还安装了Ruby 1.9.1，并安装了指南针手表的gems，并得到了相同的错误。我试图更改文件.listen_test的权限，但它不存在。
I believe this happened after upgrading to Ruby 2.0.0 and then I resintalled my gems needed for compass watch. I also installed Ruby 1.9.1 and installed the gems for compass watch and got the same error. I tried to change the permissions on the file .listen_test, but it doesn't exist.
这是--trace：
compass watch --trace

EDITI got compass watch working by installing an older version of compass (0.12.2)
推荐答案
我发现它可以用于：
sudo compass watch
我不确定为什么现在需要sudo。
I'm not sure why now I need the sudo.
