--use-local creates empty requirements.txt

[rtrrtr]

Hello,

I would like to use --use-local flag to create my requirements.txt. But unfortunately it creates an empty file (Writing 0 requirements). But --debug tells me that it has found 3 libs (Found imports: pyserial, PySimpleGUI, PyYAML).

If I use pipreqs without --use-local I get a requirements file with the 3 entries.

pipreqs version is 0.4.10 Python version is 3.8.5

with --use-local requirements.txt is empty (Writing 0 requirements)

 ✔ $ python3 -m pipreqs.pipreqs --force --debug --use-local ./
DEBUG: Found packages: {'sys', 're', 'collections', 'datetime', 'PySimpleGUI', 'io', 'itertools', 'random', 'yaml', 'serial', 'time', 'os'}
DEBUG: Found imports: pyserial, PySimpleGUI, PyYAML
DEBUG: Getting package information ONLY from local installation.
DEBUG: Writing 0 requirements:  to ./requirements.txt
INFO: Successfully saved requirements file in ./requirements.txt

without --use-local it works (Writing 3 requirements)

 ✔ $ python3 -m pipreqs.pipreqs --force --debug  ./

I'm facing the same problem. With "--use-local" the output contains only 4 lines, whatsmore the version information is different to the enviromment.
