使用Chef在Vagrant VM上安装Postgres的问题：Config：Module的未定义方法“ ruby​​” [英] Issue with installing Postgres on Vagrant VM using Chef: undefined method `ruby' for Config:Module

问题描述

这就是我的 Vagrantfile 的外观：

   config.vm.provision :chef_solo do |chef|
     chef.cookbooks_path = "cookbooks"

     chef.json = {
        postgresql: {
            password: {
                postgres: 'password'
            }
        },
        database: {
            create: ['mydb']
        },
        'build-essential' => {
            compiletime: true
        }

     }
     chef.run_list = ['recipe[build-essential]', 'recipe[openssl]', 'recipe[postgresql::server]', 'recipe[database::postgresql]']

   end  

我也使用了 precise32 框。
当我的VM在无所事事 c之后启动时，我得到非常长回溯，并显示错误消息： undefined method ruby​​'for Config：Module`。

Also I used precise32 box. And while my VM starts after vagrant up, I get very long traceback with error message: undefined methodruby' for Config:Module`.

有人吗？

推荐答案

安装 pg gem似乎存在问题：

There appears to be a problem installing the "pg" gem:

make                                                                                  
sh: 1: make: not found                         

我建议阅读 build-essentials 食谱。它建议设置 compiletime属性，以支持确保构建工具可用于编译RubyGems扩展。

I suggest reading the documentation of the build-essentials cookbook. It suggests setting the "compiletime" attribute in order to support to ensure that the build tools are available to compile RubyGems extensions.

以下json设置对我有用：

The following json settings worked for me:

chef.json = { 
  "postgresql" => {
    "password" => {
      "postgres" => "password"
    }
  },
  "database" => {
    "create" => ["encased_dev"]
  },
  "build_essential" => {
    "compiletime" => true
  }
}

注意：

• 属性是 build_essential而不是 build-essential

此后我发现有一个红宝石配方也解决了此问题（通过设置构建基本节点属性来解决）。可以将其添加到您的运行列表中，或使用数据库食谱

I have since discovered that there is a ruby recipe that fixes this issue as well (by setting the build essential node attributes about). Either add it to your run-list or use the database cookbook
