AttributeError: 'module' object has no attribute 'fspath'

[lzchen]

AttributeError: 'module' object has no attribute 'fspath' exception is thrown when running app = flask.Flask(__name__) for flask v1.13.

Version is Python 2.7 and 3.5. I realize fspath is only available for Python version >= 3.6 but there shouldn't be any breaking changes from Flask 1.1.2 => 1.1.3, so the classifiers here are actually incorrect.

Please note that Python 3.5 is no longer supported by us or CPython. Also, 1.1.x, despite being the previous release, is no longer supported due to the magnitude of the 2.x release. I advise you to use a tool like pip-compile to pin your dependencies, and/or begin upgrading to newer Python and Flask versions as soon as possible.
