npm install with Chef，导致我的流浪用户出现 EACCES 问题

Question

环境：Ubuntu Precise64 / Hosted Enterprise Chef / Vagrant

当我尝试通过 Chef 配方在我的应用文件夹中运行 NPM 安装时

execute "npm-install" do
  cwd "/home/my_user/my_nodejs_app"
  command "npm install"
  user "my_user"
  group "sudo"
  action :run
end

使用流浪盒

$ vagrant ssh
vagrant@precise64:~$ sudo chef-client

我收到此错误：

为什么 PATH 设置为 /home/vagrant/.npm，我可以解决这个问题吗？

执行资源不会接触环境，所以你必须自己设置HOME变量：

execute "npm-install" do
  # ...
  environment "HOME" => "/home/my_user"
end
