Compiler errors Windows上的Addict hex程序包依赖项错误在Mac上未发生

我尝试在我的凤凰城项目中安装该软件包，但是我遇到了一个错误。 我在一位同事的Mac电脑上尝试了完全相同的过程，他没有得到错误，而我在Windows上得到了错误。 错误来自comeonin依赖项。我也在Phoenix 0.14和昨天发布的0.15更新中尝试过

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中添加瘾君子：

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:

再次运行Phoenix项目：

结果（以下是错误）：

尝试建议：

$mix deps.compile comeonin

编辑： 在JoséValim的建议下，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：

另外，在我的Ubuntu虚拟机上安装erlang完全解决了这个问题。此问题仅在我的Windows 8.1中存在。

您需要安装nmake。引用另一个SO的回答：

nFube是微软构建C++项目的构建工具的一部分。您可以通过下载获得nmake以及MSVC++编译器。Visual C++快照在Windows 7上运行非常精细。

来源：

解决comeonin依赖性错误的说明已经更新，我按照他们的说法设法解决了这个问题：

打开Visual Studio的开发者命令提示符（在Windows 8、8.1和10中，它位于Visual Studio应用程序菜单下）

---

comeonin依赖项现在应该可以编译了。

我同时安装了Visual Studio Express和Ultimate，但它不起作用。我使用的是Windows 8.1。如果启动一个命令并键入“nmake”，会得到什么？

C:\Users\mesos\u 000>nmake“nmake”不被识别为内部或外部命令，可操作的程序或批处理文件。

我刚在/VC/bin/nmake.exe下的Visual Studio文件夹中找到它，但运行它并没有设置它。我得到

nmake:致命错误U1064:找不到MAKEFILE，也没有指定目标停止。

我使用Visual Studio Express 2015完成了此操作。我必须更改安装以确保安装C++工具。本例中的路径是

C:\ProgramFiles（x86）\Microsoft Visual Studio 14.0\VC
