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，所以它不应该与它冲突）：

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）：

编辑：

(DevContainer)which idea
/home/brandon/.nix-profile/bin/idea
(DevContainer)ls -last /home/brandon/.nix-profile/bin/idea
4 lrwxrwxrwx 1 brandon brandon 63 Jan  1  1970 /home/brandon/.nix-profile/bin/idea -> /nix/store/75sz9nklqmrmzxvf0faxmf6zamgaznfv-idea-local/bin/idea

所以它看起来像是ideaLocal作为一个环境被导入 - 将它安装为依赖于的包的正确方法是scalaEnv什么？

显然，解决方案是指定配置文件，我认为它是环境的名称，这样两个环境就不会同时安装：

nix-env -if scala-default.nix -p scala-env
