我遇到了类似的情况：Workarounds for Haskell / cabal packages with constraints with Nix and Cabal?
基本上，我有一个Haskell库，其依赖项为
time >= 1.9.2（阴谋软件包存储库中的时间库）。
nixpkgs当前似乎不存在此版本，执行nix build会导致以下错误：
...

这里有什么可能的解决方案？我也注意到以下问题，但不确定是否相关：https://github.com/haskell/cabal/issues/5223
我想到的可能的解决方案：
time包，我认为这是一个乏味的过程吗？尝试1：
myHaskellPackages = haskellPackages.override {
overrides = self: super: rec {
time = self.callCabal2nix "time" (builtins.fetchGit {
url = "git@github.com:haskell/time.git";
rev = "5d2046f79cf5451f48b17529abec85349333aa9f";
}) {};
};
};
variant = if doBenchmark then myHaskellPackages.lib.doBenchmark else pkgs.lib.id;
drv = variant (myHaskellPackages.callPackage f {});
奇怪地导致：
nix-shell
error: infinite recursion encountered, at undefined position
(use '--show-trace' to show detailed location information)
尝试2：
请记住，我对cabal并不了解，但是我只是在记录我尝试过的内容：
cabal new-update
Downloading the latest package list from hackage.haskell.org
To revert to previous state run:
cabal new-update 'hackage.haskell.org,2019-08-10T14:09:42Z'
cabal new-build

尝试3：

更新...
因此，显然覆盖time之类的'core'库实际上是行不通的（？）...我试图改为定义如下内容：
myHaskellPackages = pkgs.haskell.packages.${compiler}.override {
overrides = self: super: rec {
timezz = pkgs.haskell.packages.${compiler}.callHackageDirect
{
pkg = "time";
ver = "1.9.3";
sha256 = "1bs74nj2qc83i2d78xf1hn79f37g8wjgak2bwn5bnwb31pl0bl7r";
}
{};
};
};
然后使用timezz作为依赖项而不是time ...但是由于以下原因，它无法建立时间库：

因为最初可以使用堆栈成功构建项目，所以成功完成nix-build --option sandbox false的一种解决方法是：
{
nixpkgs ? import <nixpkgs> {}
, sources ? import ./nix/sources.nix
, compiler ? "ghc864" } :
let
niv = import sources.nixpkgs {
overlays = [
(_ : _ : { niv = import sources.niv {}; })
] ;
config = {};
};
pkgs = niv.pkgs;
in
pkgs.haskell.lib.buildStackProject {
name = "platinumpitanga";
src = ./.;
}
