Puppet：SERVER上的错误400：权限被拒绝

我想使用DOCSF模块（从github）。 如果我尝试使用它，我得到这个结果：

Error: /File[/var/lib/puppet/facts.d]: Failed to generate additional resources using 'eval_generate': Error 400 on SERVER: Permission denied - /etc/puppet/environments/production/modules/docsf/metadata.json Error: /File[/var/lib/puppet/facts.d]: Could not evaluate: Could not retrieve file metadata for puppet://puppetmaster.example.com/pluginfacts: Error 400 on SERVER: Permission denied - /etc/puppet/environments/production/modules/docsf/metadata.json Info: Retrieving plugin Error: /File[/var/lib/puppet/lib]: Failed to generate additional resources using 'eval_generate': Error 400 on SERVER: Permission denied - /etc/puppet/environments/production/modules/docsf/metadata.json Error: /File[/var/lib/puppet/lib]: Could not evaluate: Could not retrieve file metadata for puppet://puppetmaster.example.com/plugins: Error 400 on SERVER: Permission denied - /etc/puppet/environments/production/modules/docsf/metadata.json Info: Loading facts Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Permission denied - /etc/puppet/environments/production/modules/docsf/metadata.json on node pp-testexample.com Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run 

这些是模块上的文件权限：

 -r--r--r--. 1 puppet root 734 24. Jun 2014 checksums.json drwxrwxr-x. 3 puppet root 19 15. Sep 2015 lib -r--r--r--. 1 puppet root 651 15. Sep 2015 LICENSE drwxr-sr-x. 2 puppet root 71 15. Sep 2015 manifests -r--r--r--. 1 puppet root 792 15. Sep 2015 metadata.json -r--r--r--. 1 puppet root 2770 15. Sep 2015 README.md drwxr-xr-x. 2 puppet root 27 15. Sep 2015 spec drwxr-xr-x. 2 puppet root 4096 15. Sep 2015 templates drwxr-xr-x. 2 puppet root 20 15. Sep 2015 tests 

这是树：

有任何想法吗？

• 木偶4 – 获得所有连接的奴隶列表
• 使用/var/lib/puppet/.puppet/作为默认configuration目录的Puppet
• 木偶：无法find默认节点或节点test2的名称
• 在Puppet中处理模块的exception
• 木偶清单版本
