错误:无法建立隧道套接字，原因=套接字在运行 ng e2e 量角器测试时挂起

Question

我试图在我的系统中运行量角器测试，我在运行ng e2e时收到以下错误

webdriver-managerseleniumchrome-response.xml https://chromedriver.storage.googleapis.com/
i ｢wdm｣: Compiled successfully.
events.js:167

我在网上找到的有关此主题的大多数解决方案都与设置代理有关，我的代理设置为空，并且互联网未通过代理连接。有人可以帮助我解决这个问题吗？

请注意，测试用例是为我的角度应用程序编写的。
