curl-devel が足りませんでした

Welcome to the Phusion Passenger Nginx module installer, v3.0.11.

This installer will guide you through the entire installation process. It
shouldn't take more than 5 minutes in total.

Here's what you can expect from the installation process:

 1. This installer will compile and install Nginx with Passenger support.
 2. You'll learn how to configure Passenger in Nginx.
 3. You'll learn how to deploy a Ruby on Rails application.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

なんだけど、coffee-rails のところでエラーが出てしまったのでひとまず。

課題は Bundler と Gemfile の理解

続き。
「coffee-railsでエラーがでるよ」っていうのと、
そのあとにexecjsがおかしいよっていうのとあって。

• 「coffee-railsでエラーがでるよ」ってのはGemfileのバージョン指定の問題
• execjs は以下で対応可能

だった。
