Unexpected token { in re.js after updating the ionic node module

I have a module, that is malfunctioning. Uninstalling and reinstalling it ultimately results in the same error. And I can see, that uninstalling it doesn’t get rid of all the files.

Specifics:

The module in question is Ionic

The error I’m getting ever since I tried to update it is:

/usr/local/lib/node_modules/@ionic/cli/node_modules/semver/internal/re.js:1
(function (exports, require, module, __filename, __dirname) { const { MAX_SAFE_COMPONENT_LENGTH } = require('./constants')
                                                                    ^

SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:373:25)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)

    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)

it is shown whenever I run an ionic command, even ionic --help

(btw. this line, that is shown from rs.js is the first line of the file)

I’ve tried uninstalling it with npm uninstall -g @ionic/cli and npm uninstall -g ionic (I also once accidentally typed npm uninstall - ionic. and it did something…)

And reinstalling it with npm install -g @ionic/cli

Tried this several times.

I’ve also updated node to 15.6.0.

I’ve also cleaned my cache with npm cache clean --force every step of the way

I have to admit I’m generally a bit confused about node modules and where they live. Because for Ionic there are files (I’m using MacOs 11.2.3) in /usr/local/lib/node_modules/@ionic/ But also in [user folder]/node_modules/@ionic And there’s a .ionic in the user folder.

Perhaps there is something I don’t understand How do I go about issues such as this?
