Heroku 部署错误消息“conda_compile: line 7: conda: command not found”是什么意思？

如何解决Heroku 部署错误消息“conda_compile: line 7: conda: command not found”是什么意思？

我正在尝试将 conda 虚拟环境中的 django 应用程序部署到 Heroku。我正在使用 trib3 的 Heroku conda-buildpack。 Trib3 说我可以将 conda-requirements.txt 文件用于 conda 安装的软件包，也可以将 requirements.txt 用于 pip 安装的软件包。 每次我尝试部署时，我都会从 Heroku 收到相同的错误消息（见下文），“conda_compile: line 7: conda: command not found。”我不知道这是什么意思。因此，我无法解决问题。有人可以为我解释一下吗？谢谢，吉姆

public static void main(String[] args) throws java.io.IOException{

    String menu = "MENU: \n1. Science Fiction \n2. Computers and Technology \n3. Cooking \n4. Business \n5. Comics \n6. Exit";
    Scanner scanner = new Scanner(system.in); // this line

    Map<Integer,String> bookMap = new HashMap<Integer,String>();
    bookMap.put(1,"You selected Science Fiction. This is a fun topic.");
    bookMap.put(2,"You selected Computers and Technology. This is a complex topic.");
    bookMap.put(3,"You selected Cooking. This is a passionate topic.");
    bookMap.put(4,"You selected Business. This is a serIoUs topic.");
    bookMap.put(5,"You selected Comics. This is an entertaining topic.");
    // bookMap.put(6," ");

    int x;

    do {
        System.out.println(menu);
        System.out.println("Select an item from the Menu,then press Enter: ");

        x = scanner.nextInt(); // and this line

        if (x == 6)
            System.out.println("You exited the menu.");
        else {
            System.out.println(bookMap.get(x));
            if (x < 1 || x > 6)
                System.out.println("Invalid entry. Please enter a number from 1 to 6.");
            else
                System.out.print(menu);
            System.out.println("Select an item from the Menu,then press Enter.");
        }

    } while (x != 6);

}
