selenium Address already in use

在运行chromedriver 报48错误

lifedeMacBook-Pro:~ life$ chromedriver
Starting ChromeDriver 74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}) on port 9515

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
[1556790322.958][SEVERE]: bind() failed: Address already in use (48)

解决方案
先查看：

lifedeMacBook-Pro:~ life$ sudo lsof -i:9515
COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
chromedri 899 life    6u  IPv4 0x8ed22694e334ea1d      0t0  TCP localhost:9515 (LISTEN)
chromedri 899 life    7u  IPv6 0x8ed22694d83cd7dd      0t0  TCP localhost:9515 (LISTEN)

然后：

sudo kill *pid*//*部分用对应进程的PID来填充

（可用“活动监视器”来查找pid）
