Kibana bootstrapping with Yarn - Errors 800A0404/800A1391

**UPDATE 2**: Unfortunately, it doesn't work on my other computer either. While elasticsearch boots just fine, kibana.bat gives an "Unable to find usable node.js executable" message on boot. Though I know it's dangerous, I think I am just going to try to develop on the production version of Kibana from the Elastic website. Should I submit a bug request about this?

**UPDATE 1**: I went into the kibana\packages\kbn-babel-preset\node.js file & got rid of some of the commas at the end of lists/dictionary objects, which fixed the 800A0404 error, but caused another:

Line: 1
Char: 1
Error: 'module' is undefined
Code: 800A1391
Source: Microsoft JScript runtime error

Dismissing this popup allows the bootstrap to continue until hitting the eslint-import-resolver-kibana directory:

Once again: any advice is greatly appreciated!

**ORIGINAL**: I am new to Kibana plugin & JavaScript development & would appreciate some help with an error I have been attempting to troubleshoot for a little while now.

I am attempting to set up my developer environment for creating Kibana plugins as per [this guide][1]. However, I only just recently started getting the following popup error from the Windows Script Host on running the `yarn kbn bootstrap` command in the cloned kibana directory, shortly after cloning the Kibana Github directory and installing Yarn & Node.js:

Script: C:\Users\super\OneDrive\Documents\kibana\packages\kbn-babel-preset\node.js
Line: 13
Char: 9
Error: Expected identifier, string or number
Code: 800A0404
Source: Microsoft JScript compilation error

After clicking OK to dismiss this popup, here is what appears in the shell:

super@DESKTOP MINGW64 ~/OneDrive/Documents/kibana (master)
$ yarn kbn bootstrap
yarn run v1.6.0
$ node scripts/kbn bootstrap

The above error only occurs when I go to run yarn kbn bootstrap in the Git Bash terminal. Immediately after, I uninstalled/reinstalled Java v.8, v.10, Node.js, and Yarn with computer restarts in between, figuring that since the script host mentions JScript compilation that un-/reinstalling Java would help, but to no avail. Any advice would be greatly appreciated.

These errors seemed to have been caused by the Windows Script Host opening the .js files instead of Node.js.

Instead of installing Yarn manually from the official website, I installed it with `node install -g yarn` [at the suggestion of a Kibana dev][1], and these errors finally cleared up... except for the one in the /eslint-import-resolver-kibana directory but that's not the topic of this thread. :')

Thanks again to everyone who provided support!
