guard找不到libnotify，也无法禁用通知，但抛出错误

Question

guard一直运行得很好，直到它突然抛给我一堆错误：

$bin/guard
Could not open library 'libgtkmm-2.4': libgtkmm-2.4: cannot open shared object file: No such file or directory.
Could not open library 'libgtkmm-2.4.so': libgtkmm-2.4.so: cannot open shared object file: No such file or directory.

下面是一个guard notifiers命令(缩写)：

  +-------------------+-----------+------+-----------+-------------------+
  | libnotify         | ✔         | ✘    | transient | false             |
  |                   |           |      | append    | true              |
  |                   |           |      | timeout   | 3                 |
  +-------------------+-----------+------+-----------+-------------------+

  +-------------------+-----------+------+-----------+-------------------+

我尝试在Guardfile中设置notifiers :off选项，卸载libnotify gem，但没有效果。

我正在运行ubuntu服务器，所以我想我不应该有libnotify，为什么卫兵突然对我这么粗鲁？

你提到你设置的是notifiers :off，而不是notification :off (我自己总是把选项混在一起)。

此外，guard 'detects‘libnotify by requiring it here -这意味着你在系统的某个地方有这个文件。

(如果没有文件，则请求失败并返回LoadError，并且Guard判定libnotify不可用)。

一种“暴力”的方法是通过运行strace来找出它在哪里(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

对我来说这说明了：

[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:您可能安装了系统红宝石，您可以使用以下命令进行检查：

rvm use system
gem list libnotify

Guard抱怨很简单，因为gem被安装在某个地方(或者在某个地方有一个供应商提供的gem )。
