失敗啓動導軌服務器Windows 7 x 64

我開始在導軌上做一些試驗。今天我試圖啓動rails服務器，但我的Cmd引發此異常：失敗啓動導軌服務器Windows 7 x 64

我試圖重新安裝rails並運行bundle install。我在GemFile中添加了一行，但我沒有得到解決方案。我究竟做錯了什麼？

首先，Could not find a JavaScript runtime. See https://gi thub.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUn available)
第二，甚至沒有嘗試使用Windows的軌道發展，守護您的健康

謝謝antiqe爲我回答，但我也嘗試運行「gem install execjs」，但我得到了相同的結果。 – hardvin

安裝execjs和therubyracer寶石

添加以下的Gemfile

gem 'execjs' 

gem 'therubyracer'

然後運行

bundle install

Vimsha，這個愚蠢的問題的藉口，但是，窗口中的Gemfile在哪裏？我看到所有的寶石都有Gemfiles？ – hardvin

它將在您的項目根目錄中。例如，如果您的rails項目是'D：// a'，那麼您的Gemfile將位於'D：// a/Gemfile'中 – usha

嗨Vimsha謝謝你的答案。當我嘗試將這些元素添加到我的gem文件時，會得到很多新聞錯誤，那可能是一個糟糕的安裝？ – hardvin
