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

❯ 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());
                              ^

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