railsサーバを起動する方法localhost：3000 on ubuntu 12.04

Question

私は初心者です。

私は公式ページですべてを行いました。 （http://rubyonrails.org/download）

私は新しいプロジェクトを開始しようとしますが、localhost doestはubuntu 12.04では動作しません。

私はこれらのコマンドを使用します。ここでは

rails new /home/mehmet/Desktop/test/ 

は、コンソール出力です：

あなたはどんな考えを持っていますか？どのように私は新しいプロジェクトを作成することができますどのように私はlocalhost：3000を見ることができますか？

私の問題はサーバーに関するものだと思います。

Answer 1

cd /home/mehmet/Desktop/test/ 

bundle install 

rails s 

Answer 2

使用この：デフォルトのポートで実行するように

次のコマンドを使用

bundle install 
rails s 

あなたは、特定のポート番号で実行したい場合、あなたはすでに答えてい

rails s -p 3005 

Answer 3

、以下を使用します。

/usr/lib/ruby/gems/1.9.1/gems/execjs-1.4.0を/lib/execjs/runtimes.rb:51:in `autodetect '：JavaScriptランタイムが見つかりませんでした。使用可能なランタイムのリストについては、https://github.com/sstephenson/execjsを参照してください。 （ExecJS :: RuntimeUnavailable）

最も簡単な方法は、あなたのボックスにnodejsをインストールするだけです。 - apt-get install nodejsをubuntuにインストールしてください。
