Having problems getting this to work on wsl

[ImAliMoussa]

I am on a windows machine running microsoft's bash terminal, also called wsl (windows subsystem for linux) and I am unable to run material kit properly.

So I did npm run open-app and got this error:

`> material-kit@2.0.7 open-app /mnt/c/Users/ali/Desktop/webdev/tmp/material-kit-master

gulp open-app

So I open the file the material-kit-master/node_modules/opn/index.js file and scrolled to line 84 and after reading the file and a lot of console.log()'s of variables I ended up with this very very hacky solution. Basically I spawn a child process with argument 'cmd.exe' and argument absolute path to material kit index.html. Basically I removed all elements in the args array but the last one.

So I added this line:
args = [args[args.length - 1]];

before this one:
const cp = childProcess.spawn(cmd, args, cpOpts);
in the material-kit-master/node_modules/opn/index.js file/

It worked. But it doesn't watch the index.html file. So like if I added code it doesn't automatically refresh in the browser, which isn't ideal. I would appreciate any help :)
