Hi all, I am trying to build up a kibana development environment as described [here](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#development-environment-setup) and forked, then cloned the kibana [repo](https://github.com/cstock89/kibana-master.git). I´ve set up the development environment until it was failing at "npm run elasticsearch" step. I have already searched for a solution without any result. Therefore I appreciate any support. Thank you in advance. Here is the trace log: ```auto 0 info it worked if it ends with ok 1 verbose cli [ '/home/caesar/.nvm/versions/node/v6.9.0/bin/node', 1 verbose cli '/home/caesar/.nvm/versions/node/v6.9.0/bin/npm', 1 verbose cli 'run', 1 verbose cli 'elasticsearch' ] 2 info using npm@3.10.8 3 info using node@v6.9.0 4 verbose run-script ['preelasticsearch', 'elasticsearch', 'postelasticsearch'] 5 info lifecycle kibana@6.0.0-alpha1~preelasticsearch: kibana@6.0.0-alpha1 6 silly lifecycle kibana@6.0.0-alpha1~preelasticsearch: no script for preelasticsearch, continuing 7 info lifecycle kibana@6.0.0-alpha1~elasticsearch: kibana@6.0.0-alpha1 8 verbose lifecycle kibana@6.0.0-alpha1~elasticsearch: unsafe-perm in lifecycle true 9 verbose lifecycle kibana@6.0.0-alpha1~elasticsearch: PATH: /home/caesar/.nvm/versions/node/v6.9.0/lib/node_modules/npm/bin/node-gyp-bin:/home/caesar/kibana/node_modules/.bin:/home/caesar/.nvm/versions/node/v6.9.0/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin:/home/caesar/bin:/usr/lib/jvm/java-8-oracle/bin 10 verbose lifecycle kibana@6.0.0-alpha1~elasticsearch: CWD: /home/caesar/kibana 11 silly lifecycle kibana@6.0.0-alpha1~elasticsearch: Args: ['-c', 'grunt esvm:dev:keepalive'] 12 silly lifecycle kibana@6.0.0-alpha1~elasticsearch: Returned: code: 1 signal: null 13 info lifecycle kibana@6.0.0-alpha1~elasticsearch: Failed to exec elasticsearch script 14 verbose stack Error: kibana@6.0.0-alpha1 elasticsearch: `grunt esvm:dev:keepalive` 14 verbose stack Exit status 1 14 verbose stack at EventEmitter.

Seems to work OK for me. I'm on Windows and running in a gitbash shell. My output doesn't look like yours. Did you run `npm install` ? And did that work OK? My output: ```auto Lee@LeeD-ASUS MINGW64 /c/git/kibana (master) $ npm run elasticsearch > kibana@6.0.0-alpha1 elasticsearch C:\git\kibana > grunt esvm:dev:keepalive Running "esvm:dev:keepalive" (esvm) task starting up "dev" cluster Keeping elasticsearch alive, to shutdown press command/control+c INFO - - cluster - Downloading & installing from "master" branch.
