ExecJS :: RuntimeError在試驗＃指數Ruby on Rails的MongoDB的具有

錯誤消息：ExecJS :: RuntimeError在試驗＃指數Ruby on Rails的MongoDB的具有

ExecJS::RuntimeError in Tests#index Showing D:/dropWithCoffee/app/views/layouts/application.html.erb where line #6 raised: SyntaxError: [stdin]:1:1: unexpected //

我在網上嘗試以下解決方案：

：

First Solution:

在更改的文件

Ruby2.1.0\lib\ruby\gems\2.1.0\gems\execjs-2.6.0\lib\execjs\runtimes.rb

來自：

JScript = ExternalRuntime.new(
     name:  "JScript", 
     command:  "cscript //E:jscript //Nologo //U", 
     runner_path: ExecJS.root + "/support/jscript_runner.js", 
     encoding: ''UTF-16LE'' # CScript with //U returns UTF-16LE 
    )

要：

JScript = ExternalRuntime.new(
     name:  "JScript", 
     command:  "cscript //E:jscript //Nologo", 
     runner_path: ExecJS.root + "/support/jscript_runner.js", 
     encoding: 'UTF-8' # CScript with //U returns UTF-16LE 
    )

什麼都沒有改變：

Second Solution:

取消註釋在寶石文件中的以下行：
gem 'therubyracer', platforms: :ruby
和運行bundle。錯誤仍然存在。

Third Solution:

將咖啡寶石從1.9.0更改爲1.8.0版本。
我的寶石文件中的咖啡寶石是 gem 'coffee-script-source', '1.8.0' 並運行bundle update命令。沒有變化。

Fourth Solution:

移除了application.js。它解決了這個問題，但CoffeeScript的是不是裝上我的瀏覽器//= require_tree . 線。以下是我的gemfile：

source 'https://rubygems.org'

end

end 

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem 
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

Rails版本：4.2.4。
Ruby版本：2.1.5p273。操作系統：windows 7.
沒有解決方案上面的工作。

這是因爲小的語法error.I在日誌中發現的錯誤是因爲//在我file.It是因爲評論。 In .js。我們評論爲//。但是，在咖啡腳本中，我們將其評爲# .i將.js文件更改爲.js.coffee。但未註釋行。這導致了錯誤。如果這可能有幫助其他遇到同樣問題的人。
