selenium在调动页面时,报错: (unknown error: DevToolsActivePort file doesn't exist)
现象: 在两台机器上调用selenium grid进行运行时,一台机器好使,一台机器不好使。
三个自动化项目同时跑,使用的同样的chromedriver和chrome版本等,但是有一个自动化项目报如下错误,其他两个没问题
```bash
selenium.common.exceptions.SessionNotCreatedException: Message: Could not start a new session. Could not start a new session. Error while creating session with the driver service. Stopping driver service: Could not start a new session. Response code 500. Message: unknown error: Chrome failed to start: crashed.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /opt/google/chrome/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
```
