Rails gem ファイルに gem 'bitfinex-rb' を追加しました。バンドル インストールを実行すると、以下のエラーが発生しました。 

Bundler could not find compatible versions for gem "faraday":
In snapshot (Gemfile.lock):
  faraday (= 0.14.0)

In Gemfile:
  bitfinex-rb was resolved to 0.1.0, which depends on
  faraday (>= 0.9.2, ~> 0.9.2)

kucoin was resolved to 0.1.1, which depends on
  faraday (>= 0.13)

Running `bundle update` will rebuild your snapshot from scratch, using only the gems in your Gemfile, which may resolve the conflict.

これは、kucoin 0.1.1 がファラデー >= 0.13 を必要とし、bitfinex-rb 0.1.0 がファラデー ~> 0.9.2 を必要とするためです (つまり、>= 0.9.2 および <= 0.10)。少なくとも Ruby Gems には、bitfinex-rb の上位バージョンがないため、更新できます。また、他のバージョンの kucoin (0.1.0) もファラデー >= 0.13 が必要です。したがって、依存関係があるため、両方の gem (kucoin と bitfinex-rb) を同時にインストールすることはできません。バンドルは依存関係を解決しようとしますが、可能な場合にのみ実行できます。
