上传Chef食谱失败：invalid-x-ops-server-api-version

Chef服务器：12.0.8

Chef开发包（Windows）：2.1.11

C:\Data\SVN\dev\trunk\chef-repo>chef --version
Chef开发工具包版本：2.1.11
chef客户端版本：13.2.20
delivery版本：master (73ebb72a6c42b3d2ff5370c476be800fee7e5427)
berks版本：6.3.0
kitchen版本：1.17.0
inspec版本：1.33.1

该问题始于错误：

所有食谱都出现了这个问题。

所以我们向knife命令添加了详细日志记录：

knife cookbook upload acl -V -V

它显示导致错误的原因实际上是ChefDK和服务器API版本之间不匹配：

invalid-x-ops-server-api-version: "Specified version 2 not supported","min_version":0,"max_version":1

DEBUG: ---- HTTP Status and Header Data: ----

这是否意味着ChefDK v2与Chef Server v12不兼容？

根据他们的文档，Chef 12支持API版本0到3：
