syaka-syakaブログ: rails newしたらエラーになったときの対応

railsのプロジェクトを新しく作ろうとしたらエラーになったので、
そのときにやった対応です。

まずはgithubでプロジェクトだけ作ったものをcloneし、
それに大してrails newを実行。

$ bundle exec rails new .
       exist  
      create  README.rdoc
      create  Rakefile
      create  config.ru
    conflict  .gitignore
Overwrite /Users/xxx/Documents/github/test20140812/test/.gitignore? (enter "h" for help) [Ynaqdh] h
        Y - yes, overwrite
        n - no, do not overwrite
        a - all, overwrite this and all others
        q - quit, abort
        d - diff, show the differences between the old and the new
        h - help, show this help
Overwrite /Users/xxx/Documents/github/test20140812/test/.gitignore? (enter "h" for help) [Ynaqdh] n
        skip  .gitignore
    conflict  Gemfile

Resolving dependencies...
Bundler could not find compatible versions for gem "sprockets":
  In snapshot (Gemfile.lock):
    sprockets (2.12.1)
 
  In Gemfile:
    sass-rails (~> 4.0.3) ruby depends on
      sprockets (<= 2.11.0, ~> 2.8) ruby
 
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
         run  bundle exec spring binstub --all
bundler: command not found: spring
Install missing gem executables with `bundle install`

すでにあったファイルのoverwriteの確認はまぁいいとして、
Gemfileにあるsprocketsのバージョンが問題なようです。

bundle installが行われないようにいったんスキップして再度実行します。

$ bundle exec rails new . --skip-bundle

Gemfile.lockを削除します。

$ rm Gemfile.lock

bundle installを実行します。

$ bundle install --path vendor/bundle

Depending on your version of ruby, you may need to install ruby rdoc/ri data:
 
<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!

これでrailsが動くようになりました。
なんでこうなったかわからないですが、同じようにはまってる人もいたので調べることができました。
