我曾尝试查看类似问题的现有答案，但他们都发现了不同的问题，这些问题似乎无法反映我的情况。

有人有什么建议吗？

【问题讨论】：

node['cloudwatch-cookbook']['cwlogs']['logfiles']属性是如何定义的？你能发布一些例子吗？您似乎正在访问它们，因为 node['cloudwatch-cookbook']['cwlogs']['logfiles'] 是一个哈希图，但它是一个数组。
日志文件是这样定义的； 'logfile' => '@CW_LOG_FILE@', 'groupname' => '@CW_GROUP_NAME@', 'streamname' => '{instance_id}' 和属性通过 json 文件作为 "cloudwatch-cookbook" : { "cwlogs" : { "logfiles" : { "logfile" : "/var/log/syslog", "groupname" : "Project", "streamname" : "Project" }, "region" : "eu-west-1" } }

【解决方案1】：

问题是 .each 在一个 has 将返回 |key, value|。你只是抓住了 key 这是一个字符串。然后调用string['something']，它需要字符串上的索引。

如果将第 29 行更改为：

<% node['cloudwatch-cookbook']['cwlogs']['logfiles'].values do |group| -%>

你应该很高兴。
