Rake build - 找不到Gemfile

Question

當我嘗試使用rake build構建時，它說它找不到Gemfile，即使在我正在執行它的文件夾中肯定有一個...當我看它如何執行，有一個非常神祕和奇怪的cd /home/myuser/masterfolder ...我不知道爲什麼它會這樣做！下面是我在/home/myuser/masterfolder/slate運行rake build --trace與我的Gemfile在它發生了什麼，該文件夾：

** Invoke build (first_time) 
** Execute build 
cd /home/myuser/masterfolder 
bundle exec middleman build --clean 
Could not locate Gemfile 
rake aborted! 
Command failed with status (10): [bundle exec middleman build --clean...]

我想，如果這個問題是不是由於cd，感到震驚，但我只是不知道爲什麼它會去一個目錄，並找不到如何防止它。

因爲你的中間人寶石。它以不同的方式處理Gemfile。從docs：

的Gemfile

中間人將尊重捆紮機Gemfile中指定和 控制你的gem依賴。當創建一個新項目時，Middleman會爲你生成一個Gemfile文件，它指定你使用的Middleman版本相同的 版本。這將鎖定Middleman到這個 特定版本系列（例如3.0.x系列）。您還可以使用您的Gemfile使用git選項從GitHub 使用Middleman的最新版本。您在 項目中使用的所有插件和額外庫應該列在您的Gemfile中，而Middleman將在啓動時自動要求所有插件和庫。

我還沒有使用的寶石，但按照該文檔，則可能需要這樣做來打造，而不是rake build：

bundle exec middleman build
