Phoenixのインストール&実行

インストール

前回まではChef-soloを使って構築したが、Phoenixのインストールに関してはChef-soloを使うまでもなさそうなので手動でインストール

Hexパッケージマネージャをインストール

$ mix local.hex

Are you sure you want to install archive https://s3.amazonaws.com/s3.hex.pm/installs/1.0.0/hex.ez? [Yn] Y

phoenixインストール

$ mix archive.install https://github.com/phoenixframework/phoenix/releases/download/v0.13.1/phoenix_new-0.13.1.ez

Fetch and install dependencies? [Yn] Y

Phoenix uses an optional assets build tool called brunch.io
that requires node.js and npm. Installation instructions for
node.js, which includes npm, can be found at http://nodejs.org.

After npm is installed, install your brunch dependencies by
running inside your app:

    $ npm install

If you don't want brunch.io, you can re-run this generator
with the --no-brunch option.

* running mix deps.get

We are all set! Run your Phoenix application:

    $ cd sample_phoenix
    $ mix phoenix.server

You can also run it inside IEx (Interactive Elixir) as:

    $ iex -S mix phoenix.server

サーバー起動

$ cd sample_phoenix
$ mix phoenix.server
・・・
[info] Running SamplePhoenix.Endpoint with Cowboy on port 4000 (http)
[error] Could not start watcher "node", executable does not exist

なんかエラーがっ!!
どうやらnode.jsが必要らしい>< ってプロジェクト作成時にコンソールに出てますね^^;

epelリポジトリからインストール実施

$ rpm -ivh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
$ yum -y install nodejs npm --enablerepo=epel

再度サーバー起動

$ mix phoenix.server
[info] Running SamplePhoenix.Endpoint with Cowboy on port 4000 (http)

module.js:340
    throw err;
          ^
Error: Cannot find module '/home/vagrant/sample_phoenix/node_modules/brunch/bin/brunch'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:929:3

またまたエラーがっorz
localhost:4000にアクセスしてみるとこれじゃない感の画面が表示される

これもプロジェクト作成時に出てる通りnode.jsがインストールされていないせいで brunch.ioが使えていないから

という事で再度プロジェクトの作り直し

$ mix phoenix.new sample_phoenix
