Question

我在应用Puppet清单时遇到此错误：

Error: Could not apply complete catalog: Found 1 dependency cycle:
(Exec[pip install requirements] => File[change venv permissions] => File[enforce MinGW compiler] => Exec[pip install requirements])
Try the '--graph' option and opening the resulting '.dot' file in OmniGraffle or GraphViz

这是我的Puppet清单（相关部分），我没有看到任何依赖循环。有什么想法吗？

exec {'create virtualenv':
    command => "$install_dir/Scripts/virtualenv.exe venv",
    cwd     => $project_dir,
    require => Exec['install virtualenv'],
}

file { "fix Mingw32CCompiler":
    path    => "C:/Python27/Lib/distutils/cygwinccompiler.py",
    content => template($cygwinc_template),
    ensure  => present,
    require => Exec['create virtualenv'],
}

file { "enforce MinGW compiler":
    path    => "$project_dir/venv/Lib/distutils/distutils.cfg",
    owner   => $user,
    content => $mingw,
    ensure  => present,
    require => File['fix Mingw32CCompiler'],
}

exec {'pip install requirements':
    timeout => 1200,
    command => "$project_dir/venv/Scripts/pip.exe install -r $project_dir/requirements.txt",
    require => File['enforce MinGW compiler'],
}

file {'change venv permissions':
    path    => "$project_dir/venv",
    recurse => true,
    owner   => $user,
    mode    => 0770,
    require => Exec['pip install requirements'],
}

Answer 1

在puppet文件中对所声明的任何父目录都有隐式要求。

有效：

File['change venv permissions'] -> File['enforce MinGW compiler']

所以父母需要exec，exec需要孩子，而孩子需要父母，创建一个循环。

Answer 2

你最后的改变是什么（可能是你添加周期的那一刻）。

尝试使用建议来生成图表。将生成的点文件作为gist发布，以便我们进一步调查。

看看Debugging cycle or missing dependency。
