在厨师执行期间在本机扩展包之后安装gem

Question

虽然在安装本机软件包之前安装了gem,但我尝试在大厨配方中安装雾gem,因此gem安装失败

package "libxslt-dev"
package "libxml2-dev"

chef_gem "fog"

这是输出

我知道厨师资源的通知属性,但仍然可以正常运行.

那么我怎么能真正强制执行顺序首先安装本机包然后在同一个运行中安装gem.

注意:手动安装软件包不是一种选择,因为我们希望为新节点完全自动化.

为什么不尝试在资源收集阶段开始时安装依赖项,如下所述:OPSCODE wiki:从资源集合运行资源

所以你的食谱看起来像:

xsltdev = package "libxslt-dev" do
   action :nothing
end

xmldev = package "libxml2-dev" do
   action :nothing
end

xsltdev.run_action(:install)
xmldev.run_action(:install)

chef_gem "fog"
