ruby - Chef Recipe 错误 : Error Resolving Cookbooks for Run List

Question

我已经通过 knife 安装了以下 Recipe :

for cb in apt build-essential erlang java sysctl git ulimit yum yum-epel packagecloud riak curl ; do knife cookbook site install $cb; done;

现在，当我运行 sudo chef-client --local-mode --runlist 'recipe[riak]' 时，我收到一个错误，提示 git 依赖。但是，riak Recipe 包含 "git": "~> 3.0",。

安装的 git 说明书是这个版本:

$ cat /root/chef-repo/cookbooks/git/metadata.rb | grep version
version           '4.0.2'

这是命令的实际错误:

$ sudo chef-client --local-mode --runlist 'recipe[riak]'
Starting Chef Client, version 11.18.0.rc.1

非常感谢任何帮助。

knife cookbook site install 实际上并没有理解依赖项的版本。它是一个较旧的工具，早于现代 Recipe 如何处理依赖关系。我建议您改为使用 Berkshelf 来管理您的依赖项，它可以正确处理此类事情。

为了更详细地解释这个问题，~> 3.0 约束意味着从 3.0 到 4.0 的任何内容，但不包括 4.0。 knife cookbook site install 刚刚抓取了最新版本的 git cookbook，它是 4.0.2，因此超出了允许的范围。
