我正在为一个定制傀儡模块的大型存储库重构项目。 这包括从puppet 2.x升级到3.2.4。 当我终于达到临界质量并开始testing一些更改时，我迅速遇到以下错误：
Info: Retrieving plugin Info: Loading facts in /etc/puppet/modules/base/lib/facter/elversion.rb Info: Loading facts in /etc/puppet/modules/base/lib/facter/site.rb Info: Loading facts in /var/lib/puppet/lib/facter/elversion.rb Info: Loading facts in /var/lib/puppet/lib/facter/site.rb Error: Could not retrieve catalog from remote server: Error 400 on SERVER: stack level too deep at /etc/puppet/manifests/nodes.pp:9 on node puppet Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run 看过各种傀儡虫报告后，我决定尝试简化问题。 我把这个问题缩小到了两个等级，其定义如下：
class base::includes { }
和
class prod_secure::base::includes inherits base::includes { }
只包含prod_secure :: base :: includes的节点会产生上面列出的错误输出。 我在puppet-lint看到的惟一可能相关的警告是：
WARNING: class inherits across module namespaces on line 1
……但这只是一个警告，不应该让代理人傀儡崩溃，我不会想。 有任何想法吗？ 是否有可能我build立的不受木偶支持的命名空间scheme？
UPDATE
我决定继续进行testing，并更改inheritance类的名称。 新的定义是：
class prod_secure::base2::includes2 inherits base::includes { }
结果是一样的… stack level too deep 。 在我看来，这个问题与命名空间无关。
更新2
在上一轮debugging期间，我错过了一个显着的细节：

我不能说我确定为什么，但它仍然试图加载prod_secure :: base :: includes，这是违规的条目。 完全删除该文件后，testing通过。 我回到了命名空间理论
你可能想尝试傀儡3.2.3。
3.2.2有＃21376类似的问题，但固定在3.2.3，可能是回归
