how to fix Unused import statement when importing module [closed]

Question

geniuses, today I tried to convert py to exe, but it doesn't work and I got this: a Project output will not be moved to output folder Complete.

so I tried to uninstall pyinstaller with cmd, and after that my python project got broken and I got this:

Unused import statement 'from io import BytesIO'

Unused import statement 'from tkinter.filedialog import askopenfile'

Unused import statement 'from sqlite3 import Error'

Unused import statement 'Calendar

'

and when I am trying to re-installing modules by cmd so I can use the libraries correctly and import things from them I got this error too:

ERROR: Could not find a version that satisfies the requirement (module name) ERROR: No matching distribution found for (module name)

so how to correctly install them again and use them with no problem
