When I run this patch on macos-14, it passed as below.
(also run in actions: https://github.com/clover2123/jsvu/actions/runs/12031833089/job/33542249167)

I'm not sure what the problem actually is :(

Could you check by running the following command in your local environment?
If escargot were installed correctly, then it would run without any errors.

echo 'print("hello world!");' > test.js
~/.jsvu/bin/escargot test.js  // this should print `hello world!`
