排除chef-server-ctl ruby​​异常故障

Question

我刚从Chef 11升级到最新的12.x.除了必须在配置文件中删除ref to redis之外，安装和升级都很顺利。但是：

chef-server-ctrl user-create

...有这个错误的barfs：

        from /opt/opscode/embedded/bin/knife:23:in `<main>'

似乎一个文件被软管，不知何故。 ???我找不到一种方法来验证升级期间安装的所有依赖项，或者仅执行依赖项重新安装。可能导致这种情况的原因是什么？

Answer 1

事实证明，当你不知道在安装中有多少旧版本的Chef重叠时试图调试这个问题是一个无用的练习。 Chef中的任何内容都不会尝试解决依赖关系，升级的安装总是假设您要保留所有旧的，过时的东西。解决方案是进行完整备份，然后删除与Chef相关的任何内容的每个跟踪，然后再次安装所有组件并按照说明恢复备份。
