Puppet 不尊重依赖顺序？

我创建了两个Puppet模块，它们编译并安装

x264

，这取决于编译器

yasm

模块如下所示：

class yasm {
    $install_dir = "/usr/local/yasm"

    include yasm::download, yasm::compile, yasm::install
}

class x264 {
    require yasm

    $install_dir = "/usr/local/x264"

    include x264::download, x264::compile, x264::install
}

因此，当我在节点中声明对

x264

的依赖关系时，我希望

yasm

将在

x264

发生任何事情之前下载、编译和安装

然而，事实并非如此：

无论出于何种原因，我的Puppet apply都会在安装yasm之前尝试安装x264，yasm是x264的依赖项。我做错了什么？我如何表示x264完全依赖于yasm？

x264

直接依赖于

yasm

，但

yasm

不依赖任何东西

yasm

中的

include

s仅将其添加到目录中，但不为其提供任何依赖结构

一种方法是：

class yasm {
    $install_dir = "/usr/local/yasm"

    require yasm::download, yasm::compile, yasm::install
}

class x264 {
    require yasm

    $install_dir = "/usr/local/x264"

    Class['yasm'] -> class{ 'x264::download': }
    Class['yasm'] -> class{ 'x264::compile': }
    Class['yasm'] -> class{ 'x264::install': }
}

---

嗯，即使这样似乎对我也不起作用。我必须在

x264:：compile

中

要求yasm

。为什么依赖类中的需求不仅仅意味着模块顶层的需求？哎呀，我之前的错误建议是为

x264

设置依赖项，而不是为它包含的类设置依赖项，它们本身也没有依赖项。因此，将

require

直接放在需要它的类中（即

x264:：compile

）实际上是可行的。我更改了我的示例，包括为

x264:：

类添加依赖项。希望这能奏效！
