The dependent `wrapt` package no longer supports Python 2.7 on Windows

Problem statement

According to https://github.com/tantale/deprecated/blob/f5eebcddaebf2dafd3f734e85c4c85cbbae9aef4/setup.py#L161 the deprecated package depends on the wrapt package (most recent 1.*-compatible version).

Unfortunately, the wrapt package does not follow semantic versioning which means that the installation of the deprecated package might fail if a new 1.* release of the wrapt package comes out. This is what happened recently with the release of version 1.13.0 of wrapt not being able to install on Windows+Python2.7. For details refer to https://github.com/GrahamDumpleton/wrapt/issues/189. Unfortunately, the developers of wrapt do not plan to adhere to semantic versioning, which means that for deprecated to work reliably for its users, it might be a good idea to adapt the version specification of the wrapt package.

Possible solution

First, pin the version of wrapt to ==1.12.1 and release deprecated as 1.2.14 Then pin the version of wrapt to ==1.13.1 and release deprecated as 2.0.0, stating that the support for Python2.7 on Windows is dropped or drop support for Python 2.7 on all platforms (as it might be difficult to specify the combination with Windows in the setup scripts...)

Alternatives considered

After releasing deprecated v1.2.14 with wrapt==1.12.1, one could consider unpinning wrapt again (wrapt<2), however, given that wrapt does not adhere to semantic versioning, this should be considered dangerous (e.g. they consider dropping support for Python2.7 in 1.14.0).

Reproduction steps

Make sure that you do not have wrapt installed. Install deprecated on Windows+Python2.7

python -m pip install deprecated=1.2.13

Expected Behavior

The installation succeeds.

Actual Behavior

The installation fails with the following error:
