我用量角器+硒與grunt。測試在我的機器（mac）上完全在Chrome和Firefox上運行。但在CENTOS 6.5上，它不適用於Chrome。 Firefox在CENTOS機器上運行。如果我從PATH變量中刪除Chromedriver，我會得到相同的錯誤。所以我知道它不是導致問題的Chromedriver，因爲我也在量角器配置文件中指定了它。我怎麼知道這是一個硒問題還是一個chromedriver問題？我做了一個「npm install」並且有「chromedriver」：「^ 2.21.2」，「量角器」：「^ 3.3.0」，「selenium-server-standalone-jar」：「^ 2.53.0」，「 webdriver-manager「：在package.json中指定的」^ 10.0.2「。運行grunt命令時會出現什麼問題？詹金斯+ Webdriver錯誤+鉻+
我得到的錯誤是
grunt --ENV=qa --clientName=clientname --device=desktop e2e-test

你有沒有找到解決這個問題的方法？我在Jenkins量角器測試中遇到同樣的錯誤。 – JCC
@JCC我搜索了很多這個問題。雖然我還沒有找到解決方案，但我發現這個「超級（opt_error）」出現時，它似乎就像Chromedriver沒有啓動。執行以下操作：在服務器上將Java升級到1.8運行。在我的情況下，這是CENTOS 6.5機器，很遺憾，由於公司政策問題，我們無法升級。這就是說我已經使用的解決方法是讓它在Saucelabs上運行。如果你的公司沒有得到認證，我會認真推薦購買。我會很快將我的項目發佈到Github。我會在這裏發表評論。 – writetocynthia
謝謝，我可以通過安裝xvfb，無頭驅動程序，然後在Jenkins上使用相同的插件來解決此錯誤。但現在我有其他的錯誤，這不是。 – JCC
