【初心者速報】Rails実行しようとしたらExecjsがどうとか…

Posted at

環境:仮想CentOS(Red Hat)、ホストはWindows8、TeraTerm上で実行、ruby 1.9.3-p194、Rails 3.2.8

Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.

というエラーが出て、なんかこんなエラー前にもみたわ…ほらexecjsって書いてあるし…と思った今日この頃。
今回はCentOS上でのできごとですので、ちょっと勝手が違いました。

apptestというRailsファイルを作っていたので、

cd apptest
~@localhost apptest]$ vi Gemfile

のあとに、

gem 'execjs'
gem 'therubyracer'

を書き加える。そして編集を終えて、

~@localhost apptest]$ bundle install

これで実行できました。
