Vagrant 木偶Apt模块：依赖循环

在流浪汉傀儡供应器中使用

puppetlabs/apt

。该模块安装在puppet/modules中，我得到一个奇怪的依赖循环错误。 清单文件中的代码：

# Run apt-get update when anything beneath /etc/apt/ changes
#taken from https://blog.kumina.nl/2010/11/puppet-tipstricks-running-apt-get-update-only-when-needed/
exec { "apt-get update":
command => "/usr/bin/apt-get update",
onlyif => "/bin/sh -c '[ ! -f /var/cache/apt/pkgcache.bin ] || /usr/bin/find /etc/apt/* -cnewer /var/cache/apt/pkgcache.bin | /bin/grep . > /dev/null'",
}

package {
    ["build-essential","apache2","git","python","python-dev","python-setuptools", "python-pip"]:
    ensure => present,
    require => Exec["apt-get update"],
    }

class { 'apt':

        }
include apt

apt::builddep { ["python-imaging","python-lxml"]:
    require => Class['apt'] 
 }

class {'nodejs':

}
include nodejs

package {"less":
    ensure => present,
    provider => 'npm',
    require => Package['npm'],

}

事实上，我注意到了类似的问题，但答案并不令人满意。 错误消息：

有已知的工作吗？解决方案？

您的清单有点不可靠

您可以定义自己的

Exec[“apt get update”]

，尽管

apt

模块声明了一个

apt\u update

您可以使用

类{'apt'：}include apt

是冗余的。除非需要声明参数，否则请避免使用

class{}

语法

这些都是表面上的问题。可以想象，打破依赖关系的是

apt::builddep { ["python-imaging","python-lxml"]:
    require => Class['apt'] 
}

这一要求似乎没有意义，我建议您让

apt

模块处理它自己的内部依赖关系/顺序，然后它就可以工作了

apt::builddep { ["python-imaging","python-lxml"]: }

当然：-）但它并没有关闭或更新，所以我认为一些见解可能会有所帮助-如果不是对你，那么可能是未来的读者。
