Question

我正在使用Chef Solo构建一个Vagrant配置（对于Nginx，PHP和Postgres），使用databox cookbook在配置期间在Postgresql中创建数据库。我一直收到以下错误，我追溯到databox::postgresql最终调用（通过database::paostgresql）调用postgresql::ruby食谱。我尝试直接在我的运行列表中运行postgresql::ruby，它会产生相同的错误。

登录虚拟机并运行sudo /opt/ruby/bin/gem install pg有效，重新运行vagrant provision也可以。但是，正如我所理解的那样，postgresql::ruby任务的重点在于它安装了这个宝石！

以下是Chef运行的输出，该运行只运行此配方（为了便于阅读，略微编辑）：

我在这次失败的运行中没有做任何不寻常的事情 - 虚拟机是一个使用Packer构建的Vagrant Ubuntu 14.04 x64图像 - 而且Packer对图像所做的唯一事情就是安装Chef和VirtualBox扩展。

知道这里发生了什么吗？我没有看到其他人抱怨这个 - 我做错了什么或者没有其他人使用这个食谱？

Chef是版本11.12.8。

^{我还在postgresql cookbook本身上发布了这个问题，但我认为这可能会在这里得到更多曝光。}

Answer 1

看来这个问题只发生在Chef作为gem安装时，据我所知。

我从使用Chef Gem切换到使用Omnibus，我能够让它正常工作。

使用Chef安装Postgres Gem时出错
