vue.js - TypeError: this.getOptions is not a function

Question

I am facing a weird error when I installed Bootstrap. The error is below. I tried uninstalling less-loader and installing [email protected], because I saw it online, but it did nothing. I am unsure what to do at this step.

Syntax Error: TypeError: this.getOptions is not a function

Similar to what @KostDM said, in my case it seems like [email protected] doesn't work with [email protected].

I installed [email protected] and it worked like a charm again.

In your package.json:

"sass-loader": "^10",
