Cannot find package 'html-minifier-terser' imported from .../astro-single-file/index.js

[jChapman]

After running astro add astro-single-file and attempting to run dev or build I get the following error (missing dependency?)

08:48:51 PM [astro] Unable to load /home/projects/nbwiabryp.github/astro.config.mjs

 error   Cannot find package 'html-minifier-terser' imported from /home/projects/nbwiabryp.github/node_modules/astro-single-file/index.js

Did it from scratch on stack blitz and ran into the same issue, here's the full log of what I ran (also double checked that the astro config file did get updated)

Like you, I installed html-minifier-terser separately and it seems to work on macOS.

This plugin does only seem to work for single pages only i.e. a website with a nested route will not inline the CSS correctly. Astro intend to support inlining CSS natively: withastro/roadmap#556
