1. 安装Elixir/Phoenix

1.1 Exlixir 安装

  1. $ brew install elixir
  3. $ elixir -v
  4. Erlang/OTP 23 [erts-11.1.7] [source] [64-bit] [smp:6:6] [ds:6:6:10] [async-threads:1] [hipe] [dtrace]
  6. Elixir 1.11.3 (compiled with Erlang/OTP 23)

之后安装Elixir的包管理工具hex

  1. $ mix local.hex

1.2 Phoenix安装

  1. $ mix archive.install hex phx_new
  2. $ mix phx.new -v
  3. Phoenix v1.5.8

此外，Phoenix还需安装node，数据库等。

2. 测试工程

新建一个hello工程用于测试安装：

  1. $ mix phx.new hello
  2. * creating hello/config/config.exs
  3. * creating hello/config/dev.exs
  4. * creating hello/config/prod.exs
  5. * creating hello/config/prod.secret.exs
  6. * creating hello/config/test.exs

  46. * creating hello/assets/css/phoenix.css
  47. * creating hello/assets/static/images/phoenix.png
  48. * creating hello/assets/static/robots.txt
  50. Fetch and install dependencies? [Yn] y
  51. * running mix deps.get
  52. * running mix deps.compile
  53. * running cd assets && npm install && node node_modules/webpack/bin/webpack.js --mode development
  55. We are almost there! The following steps are missing:
  57.     $ cd hello
  59. Then configure your database in config/dev.exs and run:
  61.     $ mix ecto.create
  63. Start your Phoenix app with:
  65.     $ mix phx.server
  67. You can also run your app inside IEx (Interactive Elixir) as:
  69.     $ iex -S mix phx.server

运行工程，访问http://localhost:4000

  1.   $ mix phx.server

3. mix命令帮助

mix命令格式： mix task.subtask args

运行mix task 显示task 相关帮助，运行mix task.subtask显示subtask相关帮助
