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 > > /var/www/ma.lexgabrees.com/htdocs-new/node\_modules/patch-package/node\_modules/yaml/dist/compose/composer.js:33 > > if (prelude[i + 1]?.[0] !== ‘#’) > > ^ > > SyntaxError: Unexpected token ‘.’ > at wrapSafe (internal/modules/cjs/loader.js:915:16) > at Module.\_compile (internal/modules/cjs/loader.js:963:27) > at Object.Module.\_extensions…js (internal/modules/cjs/loader.js:1027:10) > at Module.load (internal/modules/cjs/loader.js:863:32) > at Function.Module.\_load (internal/modules/cjs/loader.js:708:14) > at Module.require (internal/modules/cjs/loader.js:887:19) > at require (internal/modules/cjs/helpers.js:74:18) > at Object.

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 : [https://docs.mautic.org/en/5.x/getting\_started/switching\_composer.html](https://docs.mautic.org/en/5.x/getting_started/switching_composer.html) So, it’s a clean install, and I would copy the config file into, and use the existing DB ---

@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. ---
