Rails4.2で簡単な掲示板を作ってみるテスト

はじめに

簡単な掲示板を作ることにしたので最新を試すことにした。

とりあえずこれに沿ってやる。

bundle installで下記のエラー！

terminal

$ bundle install --path vendor/bundle
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

-----
The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions.  If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

Gem files will remain installed in /Users/ms2/dev/projects/trainbbs/vendor/bundle/ruby/2.1.0/gems/nokogiri-1.6.5 for inspection.

An error occurred while installing nokogiri (1.6.5), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.5'` succeeds before bundling.

iconv足らないけど？って言われてるっぽい。コメントにそれっぽいことが出ているので下記を試したら「Command Line Tools」をインストールする？って聞かれたのでYES。

 $ xcode-select --install

あとは問題なく成功。

springが最初から動くようなのでbin/rakeとかbin/railsでコマンドを弄れば良いらしい。

$ bin/rails g scaffold comment title:string body:text status:integer
$ bin/rake db:migrate

でとりあえず簡単なコメント掲示板が完成した。ふーーー、つかれたー（何もしていない）。
