Question

我尝试在我的凤凰计划中安装addict包但是我收到了错误。我在同事的Mac上尝试了完全相同的过程，并且他没有得到错误，而我在Windows上做错了。错误来自comeonin依赖。我也曾在昨天发布的Phoenix 0.14和0.15更新中尝试过它。

重新创建的步骤：

创建一个新项目并运行它

$ mix phoenix.new testAddict
$ cd testAddict
$ mix ecto.create
$ mix phoenix.server

在mix.exs中添加addict：

defp deps do
  [{:phoenix, "~> 0.15"},
    {:phoenix_ecto, "~> 0.8"},
    {:postgrex, ">= 0.0.0"},
    {:phoenix_html, "~> 1.4"},
    {:phoenix_live_reload, "~> 0.5", only: :dev},
    {:addict, "~> 0.0.5"},
    {:cowboy, "~> 1.0"}]
end

编译依赖项：

$ mix deps.get

结果：

Running dependency resolution

  comeonin: v0.11.3
  mailgun: v0.0.2

再次运行Phoenix项目：

$ mix phoenix.server

结果（这是错误）：

尝试建议：

$ mix deps.compile comeonin

结果：

Running dependency resolution
Dependency resolution completed successfully
  comeonin: v0.11.3
$ mix phoenix.server

结果：与上述错误相同。

$ mix deps.update comeonin

结果：

修改在JoséValim的建议之后，我安装了Visual Studio Express以获得nmake。我还必须从erlang站点安装更新版本的erlang + otp。最后，我现在得到一个不同但仍然相关的错误：

C:\Users\mesos_000\Desktop\elixir Projects\testeAddict>mix deps.compile comeonin

could not compile dependency comeonin, mix compile failed. You can recompile this dependency with `mix deps.compile comeonin` or update it with `mix deps.update comeonin`

另外，在我的Ubuntu VM上安装erlang完全解决了问题。问题仍然存在于我的Windows 8.1中。

Answer 1

解决了comeonin依赖性错误的说明已经更新，我设法通过他们所说的来解决这个问题：

打开Visual Studio的开发人员命令提示符（在Windows 8,8.1和10中，它位于Visual Studio应用程序菜单下）。

$ cd "\Program Files (x86)\Microsoft Visual Studio 12.0\VC"
$ vcvarsall amd64

现在应该编译comeonin依赖。

Answer 2

您需要安装nmake。引用另一个SO回答：

NMake是Microsoft构建C ++项目的构建工具的一部分。您可以通过下载Visual C++ Express获得nmake以及MSVC ++编译器。 Visual C ++ Express在Windows 7上运行完美。

在Windows上添加十六进制包依赖项错误在Mac上不会出现
