bin/rake assets:precompile がエラーになり、ファイルが生成されない

Question

実践Ruby On Rails4を今やっているんですがassetsのプリコンパイルをやろうとしているのですが
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ ruby -e 'require "securerandom"; print SecureRandom.hex(64)' > ~/.baukis_secret_key_base
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ export SECRET_KEY_BASE='cat ~/.baukis_secret_key_base'
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ bin/rake assets:precompile
をターミナルでやってbin/rake assets:precompileをやると
下記のエラー？があり、ファイルが生成されない
何回も見直してるのですが出来ないです

追加
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ bin/rake db:create RAILS_ENV=prodution
config.eager_load is set to nil. Please update your

• development - set it to false
• test - set it to false (unless you use a tool that preloads your test environment)
• production - set it to true はこの通り編集しました

ちなみにここやるまでは本書通りに動いてました
なぜでしょう？？？？

vagrant@vagrant-ubuntu-trusty-64:/vagrant$ ruby -e 'require "securerandom"; print SecureRandom.hex(64)' > ~/baukis_secret_key_base
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ export SECRET_KEY_BASE='cat ~/baukis_secret_key_base'
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ bin/rake db:create RAILS_ENV=prodution
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

  * development - set it to false
  * test - set it to false (unless you use a tool that preloads your test environment)
  * production - set it to true

@import 'colors'; を消して実行したり、残してやったりとかしました

著者の黒田です。ls /vagrant/app/assets/javascripts コマンドの結果を教えてください。また、念のため、app/assets/stylesheets/staff/container.css.scss の中身も教えてください。

[allex]

vagrant@vagrant-ubuntu-trusty-64:/vagrant $ ls /vagrant/app/assets/javascripts application.jsです

[allex]

```@import 'colors'; @import 'dimensions'; div#wrapper { div#container { h1 { margin: 0; padding: $moderate * 1.5 $moderate; font-size: $large; font-weight: normal; background-color: $very_dark_cyan; color: $light_gray; } } } ```

Answer 1

以下を見るとRAILS_ENV指定の誤記（prodution ⇒ production）でデータベースが作成されていないのではないでしょうか。

$ bin/rake db:create RAILS_ENV=prodution
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

  * development - set it to false
  * test - set it to false (unless you use a tool that preloads your test environment)
  * production - set it to true

そこはすぐに気づきました。本当にごめんなさい
でも　bin/rake assets:precompile　でSass::SyntaxError: File to import not found or unreadable: colors.が出ます

Answer 2

著者の黒田です。

/vagrant/app/assets/javascripts ディレクトリに colors.scss というファイルが存在しないのが原因と思われます。

いま手元に書籍が持ち合わせないため明確にお答えできませんが、そういう名前のファイルを作成する手順が書籍に書いてあるのに、その手順をし忘れたのではないでしょうか。

この点について確認してください。

それでも解決法が見つからない場合は、問題が発生するソースコード全体をGitHub等で公開してください。また、書籍の何ページまで進んでいるのかを教えてください。

いま、取り組んでいるのは、p102 ~ 105です
書籍では、_colors.css.scssと書かれていました
確認して見ます

[allex]

一回ファイルを消して、もう一度ファイルを作り直してみたらエラーが出なくなりました
なぜだったのかはわからなかったですがよかったです

[allex]

丁寧な対応していただき非常に助かっています
いつもありがとうございます
