tslint.js files throws a syntax error running yarn lint on windows

Describe the bug A clear and concise description of what the bug is.

On the master branch after a successful run of yarn of this project. The yarn lint or yarn lint:fix commands fail on my windows machine. A syntax error is thrown classed as a “Microsoft JScript compilation error”. (see attached screenshot)

It looks to be a Windows specific issue where this tslint.js is being run by windows instead of node when called in package.json - similar to this SO question: https://stackoverflow.com/questions/37192508/trying-to-execute-a-script-from-package-json-on-windows-throws-a-jscript-error

Expected results

What did you expect to happen?

The yarn lint command would run to completion and lint the project source files.

Observed results

The yarn lint command throws a syntax parse error on Windows machine, pointing to the tslint.js file as the culprit. This is run straight after cloning and yarn install without any modification to the original code.

Hi @BrianJVarley. Thanks for reporting this. I have actually not run this code on a windows machine. I’ll get hold of one and look into this.

Though from the looks of it, ./tsconfig.json is mentioned on in the package.json and is not a valid path for windows environment, as far as I know. We’ll probably have to use something like cross-env. I’ll give it a shot.

If you have a proposed solution, please feel free to submit a PR. Thanks.
