如何处理‘`phoenix`’依赖版本错误问题？

Question

我想使用分页使用偏移-限制方法，并选择scrivener包.

我的私人项目的mix.exs文件如下：

  defp deps do
    [
      {:phoenix, "~> 1.6.10"},
      {:phoenix_ecto, "~> 4.4"},
      {:ecto_sql, "~> 3.6"},
      {:postgrex, ">= 0.0.0"},
      {:phoenix_html, "~> 3.0"},
      {:phoenix_live_reload, "~> 1.2", only: :dev},
      {:phoenix_live_view, "~> 0.17.5"},
      # {:floki, ">= 0.30.0", only: :test},
      {:phoenix_live_dashboard, "~> 0.6"},
      {:esbuild, "~> 0.4", runtime: Mix.env() == :dev},
      {:swoosh, "~> 1.3"},
      {:telemetry_metrics, "~> 0.6"},
      {:telemetry_poller, "~> 1.0"},
      {:gettext, "~> 0.18"},
      {:jason, "~> 1.2"},
      {:plug_cowboy, "~> 2.5"},
      {:nimble_csv, "~> 1.2"},
      {:iconv, "~> 1.0"},
      {:floki, "~> 0.33.0"},
      # {:html5ever, "~> 0.13.0"},
      {:fast_html, "~> 2.0"},
      {:mochiweb, "~> 3.1"},
      {:scrivener_ecto, "~> 2.0"},
      {:scrivener_html, "~> 1.8"}  #<--------- problem here
      #{:csv, "~> 2.5"}
    ]
  end

运行mix deps.get时，错误消息如下所示：

Failed to use "phoenix" (version 1.6.14) because
  phoenix_live_reload (version 1.3.3) requires ~> 1.4
  phoenix_live_view (version 0.17.12) requires ~> 1.6.0 or ~> 1.7.0
  scrivener_html (versions 1.8.0 and 1.8.1) requires ~> 1.0 and < 1.5.0
  mix.lock specifies 1.6.14

** (Mix) Hex dependency resolution failed, change the version requirements of your dependencies or unlock them (by using mix deps.update or mix deps.unlock). If you are unable to resolve the conflicts you can try overriding with {:dependency, "~> 1.0", override: true}

但是在scrivener的mix.exs文件中，dep信息如下，凤凰的dep< 1.7。

 defp deps do
    [
      {:scrivener, "~> 1.2 or ~> 2.0"},
      {:phoenix_html, "~> 2.2 or ~> 3.0"},
      {:phoenix, "~> 1.0 and < 1.7.0", optional: true},
      {:plug, "~> 1.1"},
      {:ex_doc, "~> 0.19", only: :dev},
      {:earmark, "~> 1.1", only: :dev}
    ]
  end

为什么出现错误消息scrivener_html (versions 1.8.0 and 1.8.1) requires ~> 1.0 and < 1.5.0

Answer 1

您所看到的文件位于scrivener_html的主分支上，而您正在添加版本1.8.1，该版本甚至不支持菲尼克斯1.5。

当它们发布一个新版本时，您可以使用{:scrivener_html, github: "mgwidmann/scrivener_html"}直接指向主分支。
