尝试构建我的项目时，我发现我缺少该库asound。
我的问题与以下位置的问题相符这libasound2线程，通过安装列出的debian 软件包解决了问题这里。
我正在运行NixOS，但没有看到libasound2可通过安装的软件包nix-env。
还有其他方法可以安装依赖项吗？可以将其添加到 NixOS 软件包列表中吗？如果是这样，我该怎么做？
我的项目构建使用 Haskell 的stack和命令$ stack build。完整输出如下所示。
$ stack build

Cabal-simple_mPHDZzAJ_1.24.2.0_ghc-8.0.2: Missing dependency on a foreign
library:
* Missing C library: asound
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
评论里建议我安装alsaLib。我尝试nix-env通过运行命令来执行此操作$ nix-env -iA nixos.alsaLib。这次尝试没有成功（我* Missing C library: asound在尝试按照此nix-env安装进行构建时遇到了相同的错误）。
答案1
我通过将以下内容放入stack.yaml.
nix:
packages: [alsaLib]
