The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

ここがわかりにくいと言った指摘やこの情報も追加して。などのコメントも待っております。よろしくお願いします。

Answer 1

gem rmagickのインストールでこけるのはだいたいImageMagickのライブラリが見つからないことが多いです。

bundle installで失敗したログの中に Magick.core がないとか、PKG_CONFIG がどうとか記述はありますか？

もしログを全部貼り付けていなければ全体を貼り付けてもらえるとさらに詳細にわかるかもしれません。

---追記---

Errno::EACCES: Permission denied @ rb_sysopen - /Users/名前/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/rmagick-2.16.0/.editorconfig

とありますね。
bundle_install　しているユーザーが、必要なファイルにアクセスできないようですね。
ユーザーの問題の気がします。

いえいえ、回答ありがとうございます。
エラーコードを読めて羨ましいです。
ユーザーに問題ですか。。。
ちょっと調べてみます。

[motozzi]

問題が2点みえます。
1.
warningもでていますが、
sudo で bundle install することもあまりないので環境構築をもう一度したほうがいいかもしれません。
ほかのgemはsudoせずにはいりましたか？

2.
rmgickはimage magickを railsで使う為の中間ソフトみたいな位置付けのgemなのですが、image magicのインストール方法によってライブラリの置かれるフォルダが変わります。
なので、そのフォルダへのパスを通すか、gemを入れるときに指定しないといけないはずです。
2についてはGoogleで検索すればでてくるはずです！

上記の記事を参考にいろんな人の力を借りてなんとかできました。

sudoでやってしまったのですが、https://teratail.com/questions/164773で解除する方法を教えてもらいなんとかrmagickを導入できました。

motozziさん、ありがとうございました！
