<p>It feels good to pickup a tutorial article, follow the step-by-step instructions and have everything working. That wasn't the case recently for me when I tried to publish a Vue component to the npm registry. In case you are interested in publishing a component, here is the article I was following  <a target="_blank" href="https://www.freecodecamp.org/news/how-to-create-and-publish-a-vue-component-library/">Create and Publish A Vue Component</a>. </p>
<p>After correcting the mistake of not running npm install after scaffolding a project with vue-sfc-rollup, I tried to startup the project with the famous <code>npm run serve</code> command of the Vue world, but I kept getting a "Babel couldn't find corejs/package.json file." It turns out this is a bug that has sort of lived on since there was an easy-enough fix for it.  Should you also run into an error like this, all you have to do is to separately install the core-js library and all will be well.</p>
