通过 aws cookbook 7.2.1 安装 aws-sigv4 (1.0.2) 时出错

Question

我正在尝试使用 aws 食谱 7.2.1 版，以便可以对 cloudformation_stack 资源使用 named_iam_capability 选项。这样我就可以为启动的实例分配一个 IAM 角色。这是在带有 Chef 12.19.36 的 Ubuntu 14.04 LTS 上运行的，但出现以下错误。

有什么办法可以解决这个错误吗？

您需要以 root 身份运行 chef-client 才能使某些功能正常工作，包括 gem 安装。在大多数 Linux 系统上使用 sudo chef-client。
