挂钩后的ChildProcess :: LaunchError发生错误：（216）

Question

我试图在Virtualbox上的IE9中使用watir-webdriver和rspec运行测试。 当我运行测试时，我收到以下错误：

An error occurred in an after hook ChildProcess:LaunchError: (216) 
occurred at F:/lib/ruby/gems/2.1.0/gems/childprocess-0.5.5/lib/childprocess/windows/process_builder.rb:87in 'create_process'

Rspec返回：

Failure/Error: let(:x) {@browser ||=Watir::Browser.new :ie} 
ChildProcess::LaunchError: (216)
G:/Test.rb:12:in 'new'
G:/Test.rb:12:in 'block (2 levels) in <top (required)>'
G:/Test.rb:13:in 'block (2 levels) in <top (required)>'

我可以在我的原生版IE10，Chrome和Firefox上运行相同的测试。

我搜索过的关于错误的一切都涉及到：
