Switching to Composer (mautic 5) - npx patch-package issue

Trying to switch Mautic 5.02 to a composer version isn’t working for me.

(mind you, I’m no composer wizard, but I’ve followed all the instructions precisely).

After running the composer create-project command, I’m getting the following exit code:

73 packages are looking for funding
run npm fund for details

npx patch-package
if (prelude[i + 1]?.[0] !== ‘#’)

SyntaxError: Unexpected token ‘.’

Anybody have an idea ?

Check if 4.4.10 → 5.0.1 fails because Symfony Path is not fount in ParameterLoader.php - #10 by peter_k helps

I’ll check that thanks … However, I already have 5.02 installed (upgraded from 4.x through the command line). I just need to switch it to a composer installation …

I am following these instructions :


So, it’s a clean install, and I would copy the config file into, and use the existing DB


Remember to execute the database migrations, etc.

@lexgabrees can you specify the nodejs and npm version you’re using?

I googled the SyntaxError: Unexpected token ‘.’ error with the file yaml/dist/compose/composer.js, and got some results related to package and nodejs version.

Locations aren’t the issue and migrations are already done … I’m running 5.02, and only trying to switch to a composer installation byt installing a new mautic instance, and copying the config files.

Nodjs : v12.22.9
NPM : 8.5.1

I’ll check if this is the issue …

So the version was the issue.

I used Snap to install the latest stable version of Nodjs (20.11.0 LTS) and this version works without any errors.
