npm run-script build doen't work.

[jh0290]

Hello I'm newbie to janus!

I can't find any solution to this error so I leave the issue.

I try to build by npm run-script build, then the error is

'$' is not recognized as an internal or external command, operable program or batch file
npm ERR! code 1
npm ERR! path C:\Users\JH\Desktop\janus-gateway-js

on WSL

The error is

Run `npm audit` for details.

$(npm bin) is a placeholder for the npm directory on linux, but won't work on windows.

If you are new to this, I'll recommend to install this package using npm:
npm i janus-gateway-js
