我正在使用带有webdriver的量角器2.1.0。我有一个我想要调试的测试，所以我输入了一个browser.pause（）命令。
it 'allows deleting level versions', ->
browser.get('/api#/costings')
element(By.id("edit")).click()
element(By.id("versions")).click()
count=element.all(By.id("listing")).count()
first=element.all(By.id("listing")).first()
browser.pause()
expect(element.all(By.id("listing")).count()).toEqual(parseInt(count) - 1)
这打开了我的测试，打开了WebDriver调试器。一旦我键入一个字符，它就会关闭Selenium。我试图输入＆＃39; repl＆＃39;进入交互模式。

Selenium Standalone has exited with code 0
Selene退出后我可以输入repl并输入类似于调试模式的内容，但由于它现在已关闭而无法连接到后端，因此我无法再执行调试命令。
如何阻止Selenium崩溃？
我已尝试更新到最新的
webdriver-manager update
selenium standalone is up to date.
chromedriver is up to date.
更新
点击＆＃39; d＆＃39;或者＆＃39; c＆＃39;导致硒关闭。
