我在应用我的Puppet清单时收到此错误：
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.有任何想法吗？
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 => $mingw,require => File['fix Mingw32CCompiler'],}
exec {'pip install requirements':
timeout => 1200,command => "$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,mode => 0770,require => Exec['pip install requirements'],}
解决方法
在puppet文件中,对于声明的任何父目录都有隐式需求.
有效：
File['change venv permissions'] -> File['enforce MinGW compiler']
因此父级需要exec,exec需要子级,而子级需要父级,创建循环.
