Double quotation mark is ignored when used with npx (on windows)

[cchangenot]

Double quotation mark is ignored when used with an "installed" version of concurrently.

With this simple package.json :

{
  "devDependencies": {
    "concurrently": "5.1.0"
  }
}

When I use npm install and then run this simple command

npx concurrently "dir /a"

I get an error because it's trying to run two commands ("dir" and "/a") instead of one ("dir /a").

• When I remove the node_modules directory, it works properly

• It also works properly when I use a globally installed concurrently

I am closing this bug as it seems to be a problem with npx.
