Unable to get the sub folder specific imports on main file

Sub folders modules are not added to file. We need to go to each sub folder and run the command, We might need to do some recursive use case where if the user is holding multiple folder as sub projects the a main requirement.txt can be produced via main folder

Reproduce the issue with a main folder containing multiple sub-project folders, then read the command entry point and the code that scans imports and writes requirements.txt. Compare output from running the command at the main folder with output from each subfolder. Done means the expected dependencies from the subfolders are represented in the generated main requirements.txt without requiring separate commands.
