title: TypeError: this.getOptions is not a function
body: <p>I am facing a weird error when I installed <a href="https://en.wikipedia.org/wiki/Bootstrap_%28front-end_framework%29" rel="noreferrer">Bootstrap</a>. The error is below. I tried uninstalling less-loader and installing less-loader@5.0.0, because I saw it online, but it did nothing. I am unsure what to do at this step.</p>
