Railsの環境構築中にbundle installをしたところ、以下のようなエラーが発生。どうやらthinというgemがエラーの原因となってる模様。とりあえずthinをインストールする必要があるみたい。

An error occurred while installing thin (1.7.2), and Bundler cannot continue.
Make sure that `gem install thin -v '1.7.2' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mailcatcher was resolved to 0.2.4, which depends on
skinny was resolved to 0.2.2, which depends on
thinエラー文の中にある以下のコマンドを実行しても、ダメだった。
gem install thin -v '1.7.2' --source 'https://rubygems.org/'【解決した方法】
gem install thin -v '1.7.2' -- --with-cflags="-Wno-error=implicit-function-declaration"なんか後ろに変なオプションを付けて実行したところ、解消できました。
-vの後ろのバージョンだけ自分の環境に出ているエラーに合わせて変えてみてください。
