我在VirtualBox上安装了全新的CentOS 6.9。我安装了puppet-agent 5.4但在应用以下清单时收到错误：
augeas { "yum_exclude_test":
incl => '/etc/yum.conf',
lens => 'Yum.lns',
context => '/files/etc/yum.conf/main',
changes => "set exclude 'dog cat'"
}
我已经尝试了默认的/etc/yum.conf文件和一个空白文件。如果我更改＆＃34;排除＆＃34;关键是＆＃34;排除＆＃34;文件已正确更新，但对于＆＃34;排除＆＃34;关键，结果如下：
excludes=dog cat
但是，我看到了：

有人知道问题是什么吗？
