Hmm, did you run yarn kbn bootstrap prior to yarn start?

[tony21177]

Hi,Lukas

After git clone kibana,I run yarn kbn bootstrap under the /kinana folder path.
It works well. But then I change the path to /kibana/plugins/test and run yarn start,It showed the message that I mentioned above.

Hi,Lukas
I find there is no cli folder under kibana/plugins?
but the plugin-helpers script require('../cli'),why?

const nodeMajorVersion = parseFloat(process.version.replace(/^v(\d+)\..+/, '$1'));
if (nodeMajorVersion < 6) {
  console.error('FATAL: kibana-plugin-helpers requires node 6+');
  process.exit(1);
}
require('../cli');

Hi,
Sorry for my ignorance of npm-link

By the way,I try the cmd below

[user1@localhost kbn-plugin-helpers]$ pwd
/home/user1/project/kibana/packages/kbn-plugin-helpers
[user1@localhost kbn-plugin-helpers]$ node cli.js start
Task "start" failed:

    at spawnSync (child_process.js:601:24)

    at module.exports (/home/user1/project/kibana/packages/kbn-plugin-helpers/tasks/start/start_action.js:43:3)
    at run (/home/user1/project/kibana/packages/kbn-plugin-helpers/lib/run.js:30:10)
    at Command.<anonymous> (/home/user1/project/kibana/packages/kbn-plugin-helpers/lib/commander_action.js:27:13)

    at Command.parse (/home/user1/project/kibana/packages/kbn-plugin-helpers/node_modules/commander/index.js:474:21)

And I console.log plugin.kibanaRoot
kbn-plugin-helpers/tasks/start/start_action.js
the result is as below

kibanaRoot:/home/user1/kibana/kibana
Task "start" failed:

why is the error kibanaRoot path?
