新しくRailsからプロジェクトを作って、それをなにもGemfile変更なしにrails serverを起動したら下記のエラーが出て

$ rails new hoge

対策

調べたところ、CoffeeScriptが入っているのでJavsacriptエンジンが必要らしいので、Gemfileに書きを追加して、解決

from /usr/lib/ruby/1.8/rubygems.rb:1082:in `gem'

調べてみると、sudoでインストールしたので、lesscのコマンドもsudoで実行しないといけないらしい。。。

$ sudo lessc hoge.less &gt; hoge.css

1	$ sudo lessc hoge.less > hoge.css

既に、Rubyの開発環境はrvmで導入済みの状態です。

せっかくなので、Roots Themeのlessでのcssを書き出しもメモしておきます。

$ cd ./wp-content/themes/roots/css/less
&#20840;&#20307;
$ sudo lessc bootstrap.less &gt; bootstrap.css
&#12524;&#12452;&#12450;&#12454;&#12488;&#31995;
$ sudo lessc responsive.less &gt; bootstrap-responsive.css

3

4

5

$ cd ./wp-content/themes/roots/css/less

全体

$ sudo lessc bootstrap.less > bootstrap.css

レイアウト系

$ sudo lessc responsive.less > bootstrap-responsive.css

ちなみに、上のRoots Themeは、標準では、css/の中にあるcssを読み込むんですが、下記のやり方だとlessの中に書き出されます。

$ sudo lessc ./less/bootstrap.less &gt; bootstrap.css
$ sudo lessc bootstrap.less &gt; ../css/bootstrap.css

1 2	$ sudo lessc ./less/bootstrap.less > bootstrap.css $ sudo lessc bootstrap.less > ../css/bootstrap.css

上記のコマンドを試したけどダメだったので、./inc/roots-actions.phpを書き換えました。
