Today, my node modules have been reset for somewhat reason(idk) and I re-installed it. It worked properly until yesterday, but this error suddenly occurred.
+) I'm using ExpressJS

You're using require. If you switch to import it should work

[Almenon]

I Looked it up and apparently it's not that simple. Imports are a es6 feature so I thought they would work in node, given that even the outdated node 6.14.4 supports the vast majority of es6 features. But apparently only the latest edition of node supports imports.

See https://stackoverflow.com/questions/45854169/how-can-i-use-an-es6-import-in-node

So if you want to use imports you have four options:

1. Use latest version of node with --experimental-modules flag. Node 8.5 might also work.
2. use babel
3. use esm
4. use typescript (highly reccomend this)

Or you can use require, like so:

let {PythonShell} = require('python-shell')

Thanks for your help!

@sni-J I found out you can still use require - see updated comment above.
