[Bug] The requirement.txt is always empty while the concern pkgs are collected by pipreqs cli

System: win 11 22621.3737
python: 3.10
pipreqs: 0.5.0

cli cmd: `pipreqs F:\AdaBins --encoding=utf8 --scan-notebooks --force`

The version infos are pasted above. I run the cli cmd in command line and get the normal standard output but the requirements.txt saved is empty.

please fix this bug soon

Start with the pipreqs CLI entry point and reproduce `pipreqs F:\AdaBins --encoding=utf8 --scan-notebooks --force` on Python 3.10 and Windows 11. Check why the collected packages do not reach the generated requirements.txt; done means the command produces a non-empty file matching the project's imports.
