Missing ParserError in dateutils.parser

[lulivi]

It seems the ParserError is missing in dateutil/parser stubs file.

Error:

module.py:12: error: Module 'dateutil.parser' has no attribute 'ParserError'
Found 1 error in 1 file (checked 1 source file)

Dateutil dir:

>>> import dateutil.parser
>>> dir(dateutil.parser)
['DEFAULTPARSER', 'DEFAULTTZPARSER', 'ParserError', 'UnknownTimezoneWarning', '__all__', '__builtins__', '__cached__', '__deprecate_private_class', '__deprecated_private_func', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', '_parser', '_parsetz', '_resultbase', '_timelex', '_tzparser', 'isoparse', 'isoparser', 'parse', 'parser', 'parserinfo']

Packages versions

Edit: add Python version

Is this issue still open? Can I take it up if it is? I'm new here.

I have a doubt. Is this as simple as adding a line in the respective file?
I found that ParseError was added in dateutil 2.8.1 according to this. So wouldn't it make a mistake if the user were using an older version of dateutil?

[JelleZijlstra]

Yes, it's probably just adding a single line to the stub file. typeshed generally tries to reflect the latest version of each library.

I've done it. Could someone review it?
