当我尝试在 json 文件中包含以下内容时：

"pattern": "^carbon\..*",

我收到错误“非法转义序列”。请问json应该怎么写呢？

谢谢。加布里埃尔

在厨师环境中,对于食谱,我有这些数组:

"envs": ["ci","ui","qa"],
"services": ["service_a","service_b","service_c","service_x"]

在模板文件中我使用了这个:

<% @envs.each do |env| %>
file {
  <%
    logfiles = ""
    @services.each do |service|
      logfiles = logfiles + "\"" + "/remotelogs/" + @env + "/" + @service + "_syslog.log\", "
    end
    logfiles = logfiles.chomp(", ")
  %>
  path           => [<%= logfiles %>]    
}
 <% end %>

我得到的错误是这样的:

no implicit conversion of nil into String

Template Context:
-----------------
on line #7
  5:       logfiles = ""
  6:       @services.each do |service|
  7:         logfiles = logfiles + "\"" …
