webpack: Cannot read property 'match' of undefined

Question

I have installed webpack (Symfony encore) using npm as follows:

sudo npm install -g @symfony/webpack-encore --save-dev

I ran this from /var/www/project

I was required to install globally due to issues with package managers and shared folders when dealing with Windows host / Linux guest.

I cannot install webpack (node_modules) in the same directory (or under it) as the /var/www/project

So my package.json file looks like this:

{   "name": "test",     "version": "1.0.0",   "description": "This is a test",   "main": "index.js",   "dependencies": {},   "devDependencies": {     "@symfony/webpack-encore": "^0.15.0"   },   "scripts": {     "test": "echo \"Error: no test specified\" && exit 1"   },   "author": "Alex",     "license": "MIT" } 

I run encore from /var/www/project using this

/usr/local/bin/encore dev

I get this lovely output in return:

Running webpack ...

What am I missing?
