Hi, @There,

$ pip install gevent --pre
$ pip install auto-py-to-exe

Explanation: auto-py-to-exe is installable on Python 3.8 on Windows without any issues (this can be verified e.g. by running pip install auto-py-to-exe --no-deps). However, it requires bottle-WebSocket to be installed, which in turn has gevent dependency. the gevent did not release a stable version that offers prebuilt wheels for Python 3.8 yet (this would be 1.5), so pip doesn't pick up prebuilt wheels and tries to build gevent==1.4 from source dist. Installing the prerelease 1.5 version of gevent avoids this.
