无法启动凤凰服务器

Question

当我致电mix phoenix.server时，我收到以下错误消息。我试过重新启动计算机。

版本：

macOS Sierra 10.12.4（16E195）

Elixir 1.4.2

依赖关系：

defp deps do
    [{:phoenix, "~> 1.2.1"},
     {:phoenix_pubsub, "~> 1.0"},
     {:phoenix_ecto, "~> 3.0"},
     {:postgrex, ">= 0.0.0"},
     {:phoenix_html, "~> 2.6"},
     {:phoenix_live_reload, "~> 1.0", only: :dev},
     {:gettext, "~> 0.11"},
     {:cowboy, "~> 1.0"}]
  end

错误消息：

我不知道为什么会遇到这个问题。

但是我通过在我的应用程序的根目录中运行sudo chmod 777 _build/dev/consolidated来修复它。
