Fixing Django/GEOS compatibility

libgeos.py

"""The version regex in django/contrib/gis/geos/libgeos.py fails on
the latest homebrew geos install at time of writing, with message:

  django.contrib.gis.geos.error.GEOSException: Could not parse version info string "3.8.0-CAPI-1.13.1 "
  
The trailing whitespace is the culprit. Add a r'\s?$' to the end of the pattern.
"""


version_regex = re.compile(
    r'^(?P<version>(?P<major>\d+)\.(?P<minor>\d+)\.(?P<subminor>\d+))'
    r'((rc(?P<release_candidate>\d+))|dev)?-CAPI-(?P<capi_version>\d+\.\d+\.\d+)( r\d+)?( \w+)?\s?$'
)

Thank you!

I have the same error on Ubuntu 20.04 and Django 1.11.25 on python2.
I fixed it by changing file /home/dima/.virtualenvs/irkru/lib/python2.7/site-packages/django/contrib/gis/geos/libgeos.py on line 196 from this:

def geos_version_info():
    """
    Returns a dictionary containing the various version metadata parsed from
    the GEOS version string, including the version number, whether the version
    is a release candidate (and what number release candidate), and the C API
    version.
    """
    ver = geos_version().decode()
    m = version_regex.match(ver)

to this:

def geos_version_info():
    """
    Returns a dictionary containing the various version metadata parsed from
    the GEOS version string, including the version number, whether the version
    is a release candidate (and what number release candidate), and the C API
    version.
    """
    ver = geos_version().decode().strip()
    m = version_regex.match(ver)

Why they don't include this simple fix in Django 1.11 update?
And why version info of the package has a trailing whitespace?

It used to work fine on Ubuntu 18, but crashes after update.
