I'm seeing build errors related to .ts files that contain #!/usr/bin/env node, which tsup tries to chmod +x in order to ensure they are executable:

If I re-run the build without deleting the dist directory first, the error does not re-occur. If I remove the scripts/extract.ts entry module from my project, the same error occurs with a different script:

I've tried and failed to reproduce this in a toy project, where I guess the generation of .d.(m)ts files runs much more quickly, and therefore all of those files are generated before tsup tries to chmod those with shebangs at the top.

Unless I'm mistaken, the .d.(m)ts files for shebang scripts don't actually need to be chmod +x; only the actual .(m)js files need to be made executable. Could this be fixed by excluding the type definition files from the shebang plug-in?
