[BUG] Npx doesn't execute my scoped package and opens its bin file in my editor

[Telokis]

What / Why

I freshly published a binary tool to help me with my projects (https://www.npmjs.com/package/@telokys/easy-typescript).
The code source can be found there if need be.
I expected to be able to run npx @telokys/easy-typescript in order to easily run my bin without even installing it.
Instead of running my script, npx opens the build/src/bin.js file inside my VSCode without executing it.
It stills prints npx: installed 12 in 4.738s but doesn't execute anything.
I tried using npx -p @telokys/easy-typescript easy-typescript but the exact same behavior occurred.

npx works fine for anything else and I just updated it (using npm i -g npm@latest) to version 6.14.2.

As a side note, I also get an annoying error about rimraf:

npx: installed 12 in 4.738s

Perhaps that file doesn't have +x set on it? bin files need to be executable.

[Telokis]

Oh I need to +x it before publishing to npm?

[ljharb]

You should anyways, for explicitness, altho i think npm will fix that for you when it's installed; but if you want it ran locally then you must.

Ok this was a very stupid issue on my end: I forgot to add a shebang to my bin file...
