“NameError：未初始化的常量Guard :: Haml :: Bundler”

在我的OSX系统上，我试图使用Guard-Haml自动将我的HAML编译为HTML。但是，当警卫正在运行并尝试编译时，我会在图1中看到下面的错误。我已安装Bunder和Guard。由于NameError：未初始化不断卫队:: Haml的::捆扎机，我试过了，安装后卫打捆为好。但是这并没有解决问题。任何需要在这里做什么的见解？“NameError：未初始化的常量Guard :: Haml :: Bundler”

感谢添

它看起来像guard-haml depends on Bundler，但仅添加it as development dependency。

我做了一个快速测试与内容的test.rb文件

::Bundler.root.to_s

使用Ruby运行失败

$ ruby test 
test:1:in `<main>': uninitialized constant Bundler (NameError)

但细bundle exec工作运行它：

$ bundle exec test

所以为了让守卫哈姆工作，你需要使用Bundler运行它：

$ bundle exec guard

热digiddy - 那工作。我不认为有一种方法可以包含bundler lib？只是跑卫。无论如何，这是诀窍。谢谢一堆。 – Nutritioustim 2013-04-28 18:22:24
