Question

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＆＃39;与之发生冲突）：

$userN = $_GET['user'];
$passW = $_GET['pass'];
$userlist = file ('auth.txt');

foreach ($userlist as $user) {
    $user_details = explode(':', $user);


    if (trim($user_details[0]) == $userN && trim($user_details[1]) == $passW) {
        $success = true;
        ECHO "Success <br />";
        break;
    }
    else {echo "failed <br />";}
}

这是nix表达式（大多数都可以忽略，但它不会太长，所以我会粘贴整个东西）：

所以看起来(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被导入为环境 - 将它作为ideaLocal的依赖项安装的正确方法是什么？

Answer 1

显然，解决方案是指定配置文件，我认为该配置文件是环境的名称，因此两个环境不能同时安装：

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

如何在Nix中使派生环境不与派生环境发生冲突？
