这不太理想，但我现在可以这样工作：

  config.vm.provisionshelldo | s | 
 s.inline =VAR1为$ 1，VAR2为$ 2
 s.args =＃{ENV ['VAR1']}＃{ENV ['VAR2']}
 end 
 

It looks like passing environment variables when calling vagrant up is simple if you're using a Ruby provisioner:

VAR=123 vagrant up

In the Vagrantfile:

ENV['VAR']

How do I do this with the :shell provisioner? Simply doing this does not seem to work:

$VAR

It's not ideal, but I got this to work for now:

config.vm.provision "shell" do |s|
    s.inline = "VAR1 is $1 and VAR2 is $2"
    s.args   = "#{ENV['VAR1']} #{ENV['VAR2']}"
end
