Syntax error setting up nuxt/vue debugging with vs code

I'm trying to set up debugging of a nuxt/vue project in vs code on win 10 . I'm using git-bash. I've found https://medium.com/@justin.ramel/nuxt-js-debugging-in-visual-studio-code-822ff9d51c77

Following the directions I've changed my package.json to

{
  "name": "nuxt4",
  "version": "1.0.0",
  "description": "My classy Nuxt.js project",
  "author": "hh",
  "private": true,
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "dev-debug": "node --inspect node_modules/.bin/nuxt",
    "generate": "nuxt generate"
  },
  "dependencies": {
    "cross-env": "^5.2.0",
    "glob": "^7.1.3",
    "nuxt": "^2.0.0",
    "vue2-google-maps": "^0.10.6",
    "vuetify": "^1.2.4",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "nodemon": "^1.11.0",
    "stylus": "^0.54.5",
    "stylus-loader": "^3.0.2"
  }
}

Launch.json:

{
 "configurations": [
{
  "type": "node",
  "request": "attach",
  "name": "Attach to Nuxt",
  "port": 9229
  }
]

}

However:

$ npm run dev-debug

> nuxt4@1.0.0 dev-debug E:\ENVS\js\nuxt4
> node --inspect=0.0.0.0 node_modules/.bin/nuxt

basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

npm ERR! Failed at the nuxt4@1.0.0 dev-debug script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

The nuxt file giving the error is:

    #!/bin/sh
    basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

    case $(uname) in
        *CYGWIN*) basedir=$(cygpath -w "$basedir");;
    esac

    if [ -x "$basedir/node" ]; then
    "$basedir/node"  "$basedir/../nuxt/bin/nuxt.js" "$@"
    ret=$?
    else 
    node  "$basedir/../nuxt/bin/nuxt.js" "$@"
    ret=$?
    fi
    exit $ret

How can I get this working?
