Question

当我认为不应该时，我收到重复的声明错误。

我正在使用以下木偶版

puppet --version
4.3.2

这是目录结构

./manifests
./manifests/site.pp
./modules
./modules/main
./modules/main/manifests
./modules/main/manifests/init.pp
./modules/main/manifests/sub.pp

site.pp

node default {
 include main
 include main::sub
}

init.pp

 class main {
  notice("main")
}

sub.pp

 class main::sub {
  notice("sub")
}

我运行此命令 puppet apply --modulepath ./modules manifests/site.pp

它产生了这个输出：

Notice: Scope(Class[Main]): main
Notice: Scope(Class[Main::Sub]): sub
Notice: Compiled catalog for black-pearl.hsd1.il.comcast.net in environment production in 0.82 seconds
Error: Duplicate declaration: Class[Main] is already declared; cannot redeclare

Answer 1

我不确定为什么会这样，也许木偶已经有了main。当我将ryan替换为main时，一切都很顺利。

$ find .
.
./manifests
./manifests/site.pp
./modules
./modules/ryan
./modules/ryan/manifests
./modules/ryan/manifests/init.pp
./modules/ryan/manifests/sub.pp

site.pp

node default {
  include ryan
  include ryan::sub
}

Answer 2

Puppet 4对名称更加严格，并且有许多保留名称，包括main：

Reserved Class Names
The following are built-in namespaces used by Puppet and so must not be used as class names:

main — Puppet automatically creates a main class, which contains any resources not contained by any other class.
