耙任務不會在軌道3

Question

我有麻煩開始與導軌3.0.0發現，因爲它只是不會加載耙任務

耙寶石：安裝

rake aborted! 
Don't know how to build task 'gems:install' 

耙-T

所以問題是，沒有包括寶石任務。 這可能也是原因，我不能安裝指南針。它給了我下面的錯誤：

是捆綁在我的系統壞了？我在雪豹身上。

Answer 1

你必須使用捆綁器，而不是rake任務。 嘗試： 捆綁安裝

如果您想安裝寶石，您必須將它們放入您的Gemfile（在項目根目錄中），然後使用捆綁軟件安裝它們。 http://github.com/schacon/bundler

在你的Gemfile：

gem "haml" 

然後運行

bundle install
