Ruby on Rails - 在Debian上安裝execjs

我想在debian上的rails上安裝ruby ...我安裝了所有東西。Ruby on Rails - 在Debian上安裝execjs

我也安裝了execjs，therubyracer和node.js。

每次我想創造一個新的控制器，它說：

/usr/local/lib/ruby/gems/2.0.0/gems/execjs-2.0.2/lib/execjs/runtimes.rb:51:in `autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)

    from bin/rails:4:in `require' 
    from bin/rails:4:in `<main>'

我安裝的execjs，therubyracer和node.js中後作出重啓...

請將您的Gemfile的副本，並給我們你怎麼會有的Ruby/Rails細節安裝在你的系統上。你在使用RVM嗎？ – Kosmonaut

爲平臺，其中有二進制版本的therubyracer gem可用，除了ruby和rubygems之外，沒有任何依賴關係。如果您的系統沒有二進制版本，那麼您需要從源代碼編譯它。要做到這一點，你的系統上必須安裝v8> 3.11.8。

嘗試增加以下到您的Gemfile

gem 'therubyracer', '0.11.0beta5' 
gem 'libv8', '~> 3.11.8'

現在，cd到你的項目，並捆綁安裝

$ cd <project> 
$ bundle install

我在rails'3.2.14'中遇到了同樣的問題，添加上面的兩個寶石幫助我擺脫了錯誤。謝謝。 – Ranjan
