'permission issue with npm init vue@latest in Ubuntu 20.04

I want to install vue 3 in a way that I choose the presets like this in my wsl2 ubuntu.

What I did was:

  1. sudo mkdir /var/www/myproj.com

  2. cd /var/www/myproj.com

  3. npm init vue@latest - but this one has EACCESS: Permission denied error

  4. So I did sudo npm init vue@latest, but this one generates the error below 

    npx: installed 1 in 3.153s
/root/.npm/_npx/3489/lib/node_modules/create-vue/outfile.cjs:5681
  const isFeatureFlagsUsed = typeof (argv.default ?? argv.ts ?? argv.jsx ?? argv.router ?? 
argv.pinia ?? argv.tests ?? argv.vitest ?? argv.cypress ?? argv.eslint) === "boolean";

SyntaxError: Unexpected token ?

From here, I honestly don't know what to do.

npm and node versions:

npm = 6.14.16
node = v14.19.1

New to linux, so please bear with me :)

I got exactly the same issue (at point 4) and updating to node 16 did the trick for me (I was still using the v12 btw).
