我试图在nixos上编译我的小项目（带有lambdacms的yesod应用程序）。但是，在使用cabal2nix（更确切地说是cabal2nix project-karma.cabal --sha256 = 0 --shell> shell.nix）之后，我仍然缺少依赖项wrt。好像是PostgreSQL。
我的shell.nix文件如下所示：
{ nixpkgs ? import <nixpkgs> {}, compiler ? "default" }:
let
inherit (nixpkgs) pkgs;
f = { mkDerivation, aeson, base, bytestring, classy-prelude

then pkgs.haskellPackages
else pkgs.haskell.packages.${compiler};
drv = haskellPackages.callPackage f {};

输出如下：

我假设没有太多丢失，所以指针会很好。
还有一点很奇怪，那就是“ nix-shell”可以工作，但随后跟着“ stack exec yesod devel”告诉我

Configuring pcre-light-0.4.0.4...
setup-Simple-Cabal-1.22.4.0-x86_64-linux-ghc-7.10.2: The program 'pkg-config'
version >=0.9.0 is required but it could not be found.
在将pkgconfig添加到我的全局配置中之后，构建似乎向前迈进了一步，因此似乎shell.nix被略微忽略了。
（到目前为止，我尝试过的信息来源：
https://groups.google.com/forum/#!topic/haskell-stack/_ZBh01VP_fo）
更新：似乎我忽略了手册的这一部分
http://nixos.org/nixpkgs/manual/#using-stack-together-with-nix
但是，想到的第一个想法
（堆栈--extra-lib-dirs = / nix / store / c6qy7n5wdwl164lnzha7vpc3av9yhnga-postgresql-libpq-0.9.1.1 / lib构建）
尚无法使用，很可能我需要使用
--extra-include-dirs或尝试其中一种。不过，看起来堆栈仍在尝试使用相同版本构建postgresql-libpq似乎很奇怪。
Update2：当前正在尝试“堆栈--extra-lib-dirs = / nix / store / 1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5 / lib --extra-include-dirs = / nix / store / 1xf77x47d0m23nbda0azvkvj8w8y77c7。包括构建”，看起来很有希望。看起来不像尼克斯路，但还是。
Update3：仍在
<command line>: can't load .so/.DLL for: /home/markus /.stack/snapshots/x86_64-linux/nightly-2015-11-17/7.10.2/lib/x86_64-linux- ghc-7.10.2/postgresql-libpq-0.9.1.1-ABGs5p1J8FbEwi6uvHaiV6/libHSpostgresql-libpq-0.9.1.1-ABGs5p1J8FbEwi6uvHaiV6-ghc7.10.2.so
(libpq.so.5: cannot open shared object file: No such file or directory) stack build 186.99s user 2.93s system 109% cpu 2:52.76 total
这很奇怪，因为libpq.so.5包含在/nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/lib中。
额外的
$LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/lib
也没有帮助。
更新4：
顺便说一句，yesod devel与堆栈执行程序yesod devel相同。我的库已下载到/ nix / store，但无法识别。
也许我需要使“ build-nix”起作用，而yesod devel在这里不起作用？
为了完整起见，这里是stack.yaml
resolver: nightly-2015-11-17
#run stack setup otherwise!!
# Local packages, usually specified by relative directory name
packages:
- '.'
# Packages to be pulled from upstream that are not in the resolver (e.g., acme-missiles-0.3)
extra-deps: [lambdacms-core-0.3.0.2 , friendly-time-0.4, lists-0.4.2, list-extras-0.4.1.4 ]
# Override default flag values for local packages and extra-deps
flags:
karma:
library-only: false
dev: false
# Extra package databases containing global packages
extra-package-dbs: []
下周末，我会退房
https://pr06lefs.wordpress.com/2014/09/27/compiling-a-yesod-project-on-nixos/
和其他搜索结果。
最佳答案
有趣，因为我自己也遇到了类似的问题-通过在stack.yaml中添加这两行来解决了这一问题：
extra-include-dirs: [/nix/store/jrdvjvf0w9nclw7b4k0pdfkljw78ijgk-postgresql-9.4.5/include/]
extra-lib-dirs: [/nix/store/jrdvjvf0w9nclw7b4k0pdfkljw78ijgk-postgresql-9.4.5/lib/]
您可能需要首先检查应该与
postgresql和/nix/store一起使用的include/中哪个lib/路径：nix-build --no-out-link "<nixpkgs>" -A postgresql
顺便说一句，如果要使用
nix-shell并且有stack可用，为什么还要使用project-karma.cabal？您是否考虑过将migrating your project与stack init ..关于mysql - nix-shell --command`stack build`导致libpq-fe.h:没有这样的文件或目录，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/34694130/
