Tried

ALLOWED_HOSTS=["]→ALLOWED_HOSTS=[*"]

Similarly, settings.py DATABASES

'NAME': os.path.join(BASE_DIR/'db.sqlite3'), →'NAME': os.path.joinstr(BASE_DIR/'db.sqlite3'),

When I changed to , the URL could not be displayed, and the migration and runserver received the following error:

TypeError: unsupported operand type(s) for /: 'str' and 'str'

The same error also occurred before changing settings.py DATABASES.

add

settings.py DATABASES

'NAME': str(os.path.join(BASE_DIR/'db.sqlite3')),

After changing to , migrate and runserver locally again, but error

 unsupported operand type(s) for /: 'str' and 'str'

Similarly, settings.py DATABASES

'NAME': os.path.join(BASE_DIR, 'db.sqlite3')),

After changing to , there are no errors in both local migration and runserve.
However, it cannot be viewed remotely.

Also, although the reference site stated that the version of Django was 3 or higher, for errors on the remote, for str recommendation,

'NAME': os.path.join(str(BASE_DIR), 'db.sqlite3')),

I tried to change to , but there were no errors in both the migration and runserve locally.
However, it cannot be viewed remotely.

Supplement (e.g., tool version)
python 3.6.9
django 2.2.7
Windows 10

The local and remote versions of Python, django have been unified.

The first error is

 argument 1 must be str, not PosixPath

As you can see, the argument that should be str is PosixPath.

How about converting the NAME to str as follows and then handing it over?

'NAME': str(os.path.join(BASE_DIR/'db.sqlite3')),

I think this link is also helpful.
