我在本地拥有最新的chromedriver，每次尝试通过双击可执行文件正常启动它时，我都可以毫无问题地启动它：
Starting ChromeDriver 2.41.578706 (5f725d1b4f0a4acbf5259df887244095596231db) on port 9515
Only local connections are allowed.
但是当我尝试将远程IP地址列入白名单时，出现以下错误：
~ $ /Users/qiushil/Downloads/chromedriver --whitelisted-ips 172.22.110.201
Starting ChromeDriver 2.41.578706 (5f725d1b4f0a4acbf5259df887244095596231db) on port 9515
All remote connections are allowed. Use a whitelist instead!
[1535393675.139][SEVERE]: bind() returned an error, errno=48: Address already in use (48)

我做了一个sudo lsof :9515，但每次都发现该端口上没有任何运行，任何人都知道如何解决此问题？预先感谢！
