Deleting empty Directory with File's Ghosts?

Question

I am trying to delete bunch of directories appearing to be empty

    amr@MacBook ~/folders> ls -la -R
total 24
drwxrwxrwx   6 amr  staff    192 Mar  9 14:37 .
drwx---r-x+ 40 amr  staff   1280 Mar  9 14:12 ..
-rw-r--r--@  1 amr  staff  10244 Mar  9 14:37 .DS_Store
drwxrwxrwx@  5 amr  staff    160 Feb 27 19:06 a
drwxrwxrwx@  5 amr  staff    160 Mar  9 14:01 b
drwxrwxrwx@  3 amr  staff     96 Feb 27 19:00 f

./a:
total 0
drwxrwxrwx@ 5 amr  staff  160 Feb 27 19:06 .
drwxrwxrwx  6 amr  staff  192 Mar  9 14:37 ..

./b:
total 0
drwxrwxrwx@ 5 amr  staff  160 Mar  9 14:01 .
drwxrwxrwx  6 amr  staff  192 Mar  9 14:37 ..

./f:
total 0
drwxrwxrwx@ 3 amr  staff   96 Feb 27 19:00 .
drwxrwxrwx  6 amr  staff  192 Mar  9 14:37 ..

amr@MacBook ~/folders> rm -r a b f
rm: a: Directory not empty
rm: b: Directory not empty
rm: f: Directory not empty
amr@MacBook ~/folders> rmdir *
rmdir: a: Directory not empty
rmdir: b: Directory not empty
rmdir: f: Directory not empty

with every possible way i could find like this , boot into recovery and trying from there , tried mv to USB and formate it with not like either and got the same message "Directory not empty" until i found this python script

import os, stat, shutil

   def remove_readonly(fn, path, excinfo):
#removes readonly tag from files/folders so they can be deleted
if fn is os.rmdir:
    os.chmod(path, stat.S_IWRITE)
    os.rmdir(path)
elif fn is os.remove:
    os.chmod(path, stat.S_IWRITE)
    os.remove(path)

shutil.rmtree('/Users/amr/folders/'',
          onerror=remove_readonly)

which gave me a new output

OSError: [Errno 2] No such file or directory: 'folders/a/0c26d4c3daf0b26cd91366caf1df3eca0bad5611e9742a0f8b409d6b80fc6a53--pixman-0.38.0.mojave.bottle.tar.gz'

other directory

OSError: [Errno 2] No such file or directory: 'folders/b/libpixman-1.dylib'

the thing is those files i already deleted manually when i tried to fix brew but wasn't able to delete the empty directory directory

Update : it seem that somehow i deleted the files but not it's extended attribute and when i try to deleted folder it tries to delete files with it's attribute but it found the attribute but not the file

sudo xattr -rc *

Move the folder to the trash. Open the trash and right click on the folder. You should see an option to "delete immediately". Select that option and folder should delete.
