rails g uploader Pictureが終わらない(Ruby on Rails Turorial)

More than 3 years have passed since last update.

rails g uploader Pictureが終わらない。

ひとまず、インストールされているgemを確認する。

gem list

carrierwave (0.10.0)
fog (1.36.0)
mini_magick (3.8.0)

上記3つの追加したgemはインストールされているようだ。

下記のブログだと、fogのバージョンを1.36.0にすればいいらしいが、ダメ。

gem updateで全部のgemをインストールし直してみる。
うまくいった。

原因がわからずもやもやするが、gemのインストールがうまく行っていないという事なのだろうか…
