deno sqlite sqlite-vss

I tried setting up sqlite-vss with Deno following these instructions but got stuck on this error

Terminal window
❯ deno task dev
Task dev deno run --allow-env --allow-read --allow-write --allow-net --unstable-ffi --allow-ffi --watch main.ts
Watcher Process started.
error: Uncaught (in promise) TypeError: readCstr is not a function
export const SQLITE_VERSION = readCstr(sqlite3_libversion());
                              ^
    at https://deno.land/x/sqlite3@0.8.0/src/database.ts:101:31
    at eventLoopTick (ext:core/01_core.js:169:7)

so I pivoted to Python. That effort eventually turned into this post.
