I'm writing a Chef cookbook to install Hubot. In the recipe, I do the following:

bash "install hubot" do
  user hubot_user
  group hubot_group
  cwd install_dir
  code <<-EOH
    wget https://github.com/downloads/github/hubot/hubot-#{node['hubot']['version']}.tar.gz && \
    tar xzvf hubot-#{node['hubot']['version']}.tar.gz && \
    cd hubot && \
    npm install
  EOH
end

However, when I try to run chef-client on the server installing the cookbook, I'm getting a permission denied writing to the directory of the user that runs chef-client, not the hubot user. For some reason, npm is trying to run under the wrong user, not the user specified in the bash resource.

I am able to run sudo su - hubot -c "npm install /usr/local/hubot/hubot" manually, and this gets the result I want (installs hubot as the hubot user). However, it seems chef-client isn't executing the command as the hubot user. Below you'll find the chef-client execution. Thank you in advance.
