Question

guard运行正常，直到突然出现，它抛出了这些错误：

$bin/guard

这是guard notifiers命令（缩写）：

  +-------------------+-----------+------+-----------+-------------------+
  | libnotify         | ✔         | ✘    | transient | false             |

我已尝试在Guardfile中设置notifiers :off选项，卸载libnotify gem，但它没有效果。

我正在运行ubuntu服务器，所以我觉得我不应该有libnotify，为什么警卫突然对我这么粗鲁？

你提到你设置了notifiers :off，而不是notification :off（我自己总是混淆了这些选项）。

此外，警卫＆＃39;检测＆＃39; libnotify by requiring it here - 这意味着您的系统中有文件。

（如果没有文件，要求失败并出现LoadError并且Guard决定libnotify不可用）。

蛮力＆＃34;通过运行strace找出它的位置（应该在服务器上可用）：

strace -f -e open bundle exec guard notifiers 2>&1 | /bin/grep -v 'ENOENT' |/bin/grep lib/libnotify.rb

对我来说，显示：

[pid 16703] open("/home/me/.rvm/gems/ruby-2.1.4@guard/gems/libnotify-0.9.0/lib/libnotify.rb", O_RDONLY|O_CLOEXEC) = 7
[pid 16703] open("/home/me/.rvm/gems/ruby-2.1.4@guard/gems/libnotify-0.9.0/lib/libnotify.rb", O_RDONLY|O_CLOEXEC) = 7

注意：您可能安装了系统红宝石，可以查看：

rvm use system
gem list libnotify

Guard只是抱怨因为宝石安装在某个地方（或者某个地方有宝石）。

guard无法找到libnotify也无法禁用通知但是抛出错误
