【问题描述】：
我在尝试构建一个环境时遇到以下冲突错误，据我所知，该环境不应该发生冲突（在这种情况下，scala-env 依赖于ideaLocal，因此它不应该与它冲突):
...

这是 nix 表达式（大部分可以忽略，但不会太长，所以我会粘贴整个内容）：
with import <nixpkgs> { };
let
ideaLocal = stdenv.mkDerivation {
name = "idea-local";
buildInputs = [ ];
builder = builtins.toFile "builder.sh" ''
source $stdenv/setup
mkdir -p $out/bin
tar zxvf $src -C $out/
ln -sf $out/idea-IU* $out/idea
ln -sf $out/idea/bin/idea.sh $out/bin/idea
'';
shellHook = ''
IDEA_JDK=/usr/lib/jvm/zulu-8-amd64
'';
src = fetchurl {
url = https://download.jetbrains.com/idea/ideaIU-2017.2.4-no-jdk.tar.gz;

};
priority = 5;
};

buildEnv {
name = "scala-env";

所以看起来 ideaLocal 正在作为环境导入 - 将其安装为依赖于 scalaEnv 的包的正确方法是什么？
【问题讨论】：

我看到正在构建两个“用户环境”。第一个成功，第二个失败。您是否有可能正在构建您的环境，然后将其安装到您的用户环境中（使用
nix-env），您的声明性环境（被视为包含bin/idea的普通包）与预先存在的@987654328 命令式安装相冲突@? -
@RobertHensing 谢谢 - 查看我的编辑。
