Gauge can run well in my local machine ,but When I run it in one agent of the Go CD，the error console is:

Hi,

This line from your stacktrace seems to suggest that there is an issue starting Chrome:

> Chrome failed to start: crashed

I guess you might have to look at the agent's logs to figure out the root cause. Also, you could verify that chrome is installed on the agent and is available for the gocd user.

regards

Thanks for you reply.I installed ChromeDriver on the agent, need I install the whole Chrome or just ChromeDriver is ok? 

The ChromeDriver start console is :

:compileJava UP-TO-DATE

:processResources UP-TO-DATE

:classes UP-TO-DATE

:compileTestJava UP-TO-DATE

:processTestResources UP-TO-DATE

:testClasses UP-TO-DATE

:gauge

Hey,

You will have to install Chrome as well. ChromeDriver just gives you hooks to interact with Chrome.
