在测试厨房中以特定用户身份运行命令

我知道您可以在Chef recipes中运行“execute”模块,它包含一个cwd和用户参数,允许您在当前工作目录中以该用户的身份运行命令。这就是我在代码中所做的:

execute 'rpmdev-setuptree' do
   user 'rpmbuild'
   cwd '/home/rpmbuild'
   live_stream true
   action :run
end

我一直在以root用户身份执行此命令或显式更改目录(即执行“cd/home/rpmbuild&rpmdev setuptree”),但这不起作用。Chef似乎下定决心,无论我做什么,都要在/根目录下运行此命令。为什么会这样?请注意,我一直在做:

execute 'cd /home/rpmbuild  && rpmdev-setuptree' do
   user 'rpmbuild'
   cwd '/home/rpmbuild'
   live_stream true
   action :run
end

或

execute 'sudo su - rpmbuild  && rpmdev-setuptree' do
   user 'root'
   cwd '/home/rpmbuild'
   live_stream true
   action :run
end 

有人能告诉我为什么会这样吗?我试图在/home/rpmbuild目录中运行rpmdev setuptree,以便它构建出路径,但它总是在/root目录中运行此命令。

输出在我运行的代码段之间有所不同,有些代码段已完成,但没有输出。但我没有注意到,当尝试单独使用rpmdev setuptree时,它会:
