Ruby on rails 进程意外关闭，状态为1，firefox webdrivers位于watir（ruby on rails）中

我有rails应用程序

gem 'headless'
gem 'watir'
gem 'webdrivers'
gem 'watir-screenshot-stitch'
gem 'watir-scroll'

我在debian 9上，我已经安装了

sudo apt获取安装firefox esr

firefox-esr -v
Mozilla Firefox 52.9.0

我在这里下载了geckodrivers的最新版本v0.21.0，我在

~/.webdrivers/

但是，当我尝试启动浏览器时，

browser=Watir:：browser.new:firefox，headless:true

我有一个即时错误：

Process unexpectedly closed with status 1

response.rb line 32 in initialize

webdriver.rb line 86 in for

我尝试清除并重新安装FF

我试着用v0.19.1来描述壁虎河

但什么都不管用，我不知道如何有更多的日志进行调试

编辑：使用

Selenium:：WebDriver.logger.level=：debug

我得到：
