上運行時，窗口沒有JavaScript運行軌道服務器

我完全新的Ruby on Rails的，和我有麻煩設置它我的Windows PC上。我已成功按照http://rubyonrails.org/download的說明操作。然而，當我去運行rails server命令我想出這個輸出：上運行時，窗口沒有JavaScript運行軌道服務器

當我去的網站https://github.com/sstephenson/execjs我仍然不確定如何進行。 有人可以指出我正確的方向（記得我是一個新手）？謝謝！

這可能不是一個普遍流行的答案，但對於一個新用戶，我會註釋掉的Gemfile正在加載的青菜和CoffeeScript的線條。並不是說他們一點都不好 - 但我認爲他們爲了解框架而增加了不必要的複雜性。另外，如果你已經熟悉了這些組件，那麼你只需要安裝-I使用node.js

不要打破框架，讓它運行。另外，Sass和Coffeescript的改進太大，簡單地忽略。 –

我做你的建議 - 禁用青菜和CoffeeScript的寶石 - 和它的作品！不過，我得弄清楚，一旦我想結合JavaScript，但我仍然在試圖讓我周圍的回報率是如何工作的頭，所以這個工程現在。謝謝！ – Abundnce10

我遇到了這個問題太一個JavaScript運行時對我來說，解決方案只是增加

C:\Windows\System32

到PATH

並重新啓動計算機。

我把它通過安裝的node.js從http://nodejs.org/（安裝鏈接）工作，並加入其安裝路徑（包括node.exe）到我的Windows用戶路徑「環境變量。我還將楊的回覆路徑添加到了上面提到的windows變量中。
