Hi!

Excuse me, but is this a TSX-related bug? It works for me even on v4.7.0 — a release from two years ago.

$ /tmp echo "console.log(import.meta.dirname);console.log(import.meta.filename);" > test.js
tsx test.js
/private/tmp
/private/tmp/test.js
$ /tmp tsx -v
tsx v4.7.0
node v25.8.2

Is your Node.js version up to date?

It works at tsx v4.7.0 but failed at tsx v4.21.0, tried both node v24 and v25.
