Can't run changedetection.io on windows after updating to version 0.39.

On Windows operating system, changedetection crashes after updating to version 0.39. It gives the error ValueError: urls must start with a leading slash right on launch. Seems to be caused by the code below

#changedetectionio/__init__: line 46
# Needs to be set this way because we also build and publish via pip
base_path = os.path.dirname(os.path.realpath(__file__))
app = Flask(__name__,
             static_url_path="{}/static".format(base_path),
             template_folder="{}/templates".format(base_path))

On windows, base_path starts with drive letters C, D, or E. Flask does not accept such path as static_url_path. On Linux, everything works fine. I have no experience in Python to create a PR

Sorry we dont support native windows yet... but sometime soon yes

[dgtlmoon]

I'm open to PRs tho

When I find a windows VM machine that works i'll take a look

[tienquanutc]

Static files have been handled by the route @app.route("/static/<string:group>/<string:filename>", methods=['GET']). I think removing static_url_path param doesn't affect changedetection working

[dgtlmoon]

I see that paths are also absolute, and they probably dont need to be (atleast by default)

.. I need a windows VM :(

I had this problem too. this thread has one part of a solution by user Susensio, basically you'll have to change blueprints.py line 250: self.add_url_rule( '/static' + '/<path:filename>', view_func=self.send_static_file, endpoint="static", ... and in app.py line 602: self.add_url_rule( '/static' + '/<path:filename>', endpoint="static", ...

and I think you'll also have to be using python 3.8 to avoid a separate issue. this means you might have to do something like "py -3.8 changedetection.py -d C:\Users\Owner\Desktop\changedetection -p 5000" to run it. I just wanted to include that in case you run into it too

[dgtlmoon]

we dont use blueprints.py hmm

[Lisawitz]

oh yeah, I tested it and it does seem like you only need to make that small change to app.py. blueprints.py doesn't need to be changed if it's not used.

there was an upgrade to flask recently, I think it may have solved this issue, can you retest?
