Protractor 量角器-webdriver管理器开始提供（RunTimeException:java.net.BindException:Address ready in use:bind）

当我使用webdriver管理器start命令启动服务器时，会出现以下错误。我在全球范围内安装了量角器和webdriver管理器

通常，当端口已在使用时会发生这种情况。Webdriver默认使用端口：4444。似乎4444端口已经在使用中。尝试使用其他端口

可以使用以下命令启动具有不同端口的web驱动程序：

webdriver管理器启动--seleniumPort=XXXX例如（4445）
