Hi  
I was trying to setup kibana 6.3.0 development environment and bootstrap it for using its in-build plugin generator to develop kibana plugin. But when I amgetting an error in between bootstrapping steps.

The error is as follows:

Installing dependencies in [@kbn/es]:

[1/4] Resolving packages...  
[2/4] Fetching packages...  
[3/4] Linking dependencies...  
error An unexpected error occurred: "Reduce of empty array with no initial value".

Could you please find the reason for this error and suggest a work around. Or any other alternative way to develop kibana plugin.

Thanks  
George

What version of `yarn` are you using? I believe there's an issue with 1.7.0, which I thought was the cause of this error for some people internally. I know for sure that version 1.6.0 works as expected.
