「NameError：未初始化的常量Guard :: Haml :: Bundler」

在我的OSX系統上，我試圖使用Guard-Haml自動將我的HAML編譯爲HTML。但是，當警衛正在運行並嘗試編譯時，我會在圖1中看到下面的錯誤。我已安裝Bunder和Guard。由於NameError：未初始化不斷衛隊:: Haml的::捆紮機，我試過了，安裝後衛打捆爲好。但是這並沒有解決問題。任何需要在這裏做什麼的見解？「NameError：未初始化的常量Guard :: Haml :: Bundler」

感謝添

它看起來像guard-haml depends on Bundler，但僅添加it as development dependency。

我做了一個快速測試與內容的test.rb文件

::Bundler.root.to_s

使用Ruby運行失敗

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

但細bundle exec工作運行它：

$ bundle exec test

所以爲了讓守衛哈姆工作，你需要使用Bundler運行它：

$ bundle exec guard

熱digiddy - 那工作。我不認爲有一種方法可以包含bundler lib？只是跑衛。無論如何，這是訣竅。謝謝一堆。 – Nutritioustim 2013-04-28 18:22:24
