从 Windows 7 运行 Codeception 时出现 Web 驱动程序错误

问：

我正在 Windows 7 机器上运行我的 codeception 验收测试，这导致了下面提到的问题。

Signature: somethingSearchCept
Test: tests\acceptance\test\tstCases_somethingSearch\somethingSearchCept.php
Scenario --
  WebDriver::debugWebDriverLogs method has been called when webDriver is not set

  WebDriver::_saveScreenshot method has been called when webDriver is not set
  WebDriver::_savePageSource method has been called when webDriver is not set
  Screenshot and page source were saved into 'D:\Training\codeception\tests/_out
put\' dir
 ERROR

in phar://D:/Training/codeception/codecept.phar/src/Codeception/Module/WebDriver
.php:729
this is the error on debug mode

当我从 Windows 10 机器上运行它时，它运行良好并执行验收测试。下面是我拥有的配置yml。

actor: Tester
paths:
    tests: tests
    log: tests/_output
    data: tests/_data
    support: tests/_support
    envs: tests/_envs
settings:
    bootstrap: _bootstrap.php
    colors: false
    memory_limit: 1024M
extensions:
    enabled:
        - Codeception\Extension\RunFailed

我使用的 Selenium Web 驱动程序版本是 3.4.0。PHP 版本为 5.6。我已经下载了最新的 chrome 驱动程序版本 2.30。我在这里做错了什么？任何帮助将不胜感激。

acceptance.suite.yml内容如下。

# Codeception Test Suite Configuration
#
# Suite for acceptance tests.
# Perform tests in browser using the WebDriver or PhpBrowser.
# If you need both WebDriver and PHPBrowser tests - create a separate suite.
