Yes.
It should work.

try also: $ npm i @traptitech/markdown-it-spoiler --save

This dependency was not found:

• /markdown-it-spoiler in ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/components/Editor.vue

To install it, you can run: npm install --save /markdown-it-spoiler
