我已经按照nixpkgs手册的declarative package management设置了本地nix配置。
我想将idea-ultimate作为myPackages之一，但目前对jetbrains jdk的依赖项是broken，指向macOS上不存在的软件包。
正在尝试下载jbrsdk-11_0_2-osx-x64-b485.1.tar.gz而不是jbrsdk-11_0_4-osx-x64-b485.1.tar.gz。
[我以为我可以通过如下重写jetbrainsjdk来解决此问题，但是当我执行error: attribute 'jetbrainsjdk' missing, at /Users/ldeck/.config/nixpkgs/config.nix:4:20之类的操作时，就会得到nix-env -qa ‘jetbrains.*’。
重写idea-ultimate以便使用固定的jdk的正确方法是什么？
这里是我的~./config/nixpkgs/config.nix。
{
allowUnfree = true;
packageOverrides = pkgs: rec {
jetbrainsjdk = pkgs.jetbrainsjdk.override {
version = "520.11";
src = pkgs.fetchurl {
url = "https://bintray.com/jetbrains/intellij-jdk/download_file?file_path=jbrsdk-11_0_4-osx-x64-b${jetbrainsjdk.version}.tar.gz";
sha256 = "0d1qwbssc8ih62rlfxxxcn8i65cjgycdfy1dc1b902j46dqjkq9z";
};
};
myProfile = pkgs.writeText "my-profile" ''
export PATH=$HOME/.nix-profile/bin:/nix/var/nix/profiles/default/bin:/sbin:/bin:/usr/sbin:/usr/bin
export MANPATH=$HOME/.nix-profile/share/man:/nix/var/nix/profiles/default/share/man:/usr/share/man

myPackages = with pkgs; buildEnv {

'')

};
};
}
UPDATE 1
感谢@ChrisStryczynski，他建议我需要with pkgs，我走得更远。
但是现在的问题是，在尝试使用自定义jdk安装最终版本的想法时，仍然需要从某个位置断开，不存在的jbrsdk-11_02-osx-x64-b485.1.tar.gz.drv。
以下更新的配置和日志。

allowUnfree = true;

});

而不是：
nix-env -iA nixpkgs.myPackages
只需：
nix-env -iA nixpkgs.myIdeaUltimate
问题是：
myPackages = with pkgs; buildEnv {
...
myIdeaUltimate
];
...
};
这里您仍在引用旧的pkgs.myIdeaUltimate。
Nixos似乎做了一些处理，用pkgs中的相应内容替换packageOverrides。
感谢Danylo Hlynskyi通过discussion on discourse.nixos.org titled “How do you discover the override attributes for a derivation"，使用叠加层找到了解决方案。
〜/ config / nixpkgs / overlays / 02-jetbrains.nix
self: super:
{
jetbrains = super.jetbrains // {
jdk = super.jetbrains.jdk.overrideAttrs (oldAttrs: rec {
version = "520.11";
src = super.fetchurl {
url = "https://bintray.com/jetbrains/intellij-jbr/download_file?file_path=jbrsdk-11_0_4-osx-x64-b520.11.tar.gz";
sha256 = "3fe1297133440a9056602d78d7987f9215139165bd7747b3303022a6f5e23834";
};
passthru = oldAttrs.passthru // {
home = "${self.jetbrains.jdk}/Contents/Home";
};
});
idea-ultimate = super.jetbrains.idea-ultimate.overrideAttrs (_: {
name = "idea-ultimate.2019.2.4";
src = super.fetchurl {
url = "https://download.jetbrains.com/idea/ideaIU-2019.2.4-no-jbr.tar.gz";
sha256 = "09mz4dx3zbnqw0vh4iqr8sn2s8mvgr7zvn4k7kqivsiv8f79g90a";
};
});
};
}
安装：nix-env -iA 'nixpkgs.jetbrains.idea-ultimate’。
执行：idea-ultimate。
难题的关键部分是重写passthru.home变量以指向覆盖的jdk，而不是super所需的jdk。否则，您将下载旧的jdk以用于运行时。
passthru = oldAttrs.passthru // {
home = "${self.jetbrains.jdk}/Contents/Home”;
};
没有附加/Contents/Home，因为self.jetbrains.jdk不是有效的住所，所以创意无法启动。
