如何修复在Windows上编译bcrypt_elixir或argon_elixir的错误？

Question

我正在尝试在elixir / phoenix中创建一个带有身份验证的Web应用程序。 尝试使用mix deps.compile或者混合phx.server编译argon_elixir或bcrypt_elixir时，我遇到了nmake的错误。如何正确配置nmake以便能够编译包？

我已经安装了visual studio和c ++构建工具并将nmake设置为我的路径。 然后在使用vcvarsall.bat amd64的相应路径设置命令提示符后运行命令mix deps.compile后，出现以下错误：

could not compile dependency :argon2_elixir, "mix compile" failed. You can recompile this dependency with "mix deps.compile argon2_elixir", update it with "mix deps.update argon2_elixir" or clean it with "mix deps.clean argon2_elixir"

** (Mix) Could not compile with "nmake" (exit status: 2).
One option is to install a recent version of
[Visual C++ Build Tools](http://landinghub.visualstudio.com/visual-cpp-build-tools)
either manually or using [Chocolatey](https://chocolatey.org/) -
`choco install VisualCppBuildTools`.

After installing Visual C++ Build Tools, look in the "Program Files (x86)"
directory and search for "Microsoft Visual Studio". Note down the full path
of the folder with the highest version number. Open the "run" command and
type in the following command (make sure that the path and version number
are correct):

    cmd /K "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" amd64

This should open up a command prompt with the necessary environment variables
set, and from which you will be able to run the "mix compile", "mix deps.compile",
and "mix test" commands.

尝试打开Developer Command Prompt并在该shell中重新运行该命令。 在路径上拥有nmake本身并不足够; 编译器还依赖于需要设置的一些环境变量（例如LIB）。 实际上，您收到的错误消息告诉我没有设置那些环境变量。

Developer Command Prompt设置这些环境变量。
