Error installing on Python 3.9

[BrianMSheldon]

Pretty sure this is the same issue as #126 but its really annoying that this occurs for every new python release, especially since the first 3.9 testing release has been out for almost a year and final is supposed to be out in a week.. Sorry didn't see readme explicitly states that python 3.8+ are not supported.

[gvanrossum]

I think the fix will be separate though, so it's useful to track this separately.

Also, while no effort will be made to support parsing Python 3.8+ using typed_ast, we may want to support parsing Python 2.7 for mypy for quite a while longer, and (once 3.9 is really out :-) it would be a bit annoying (though not truly prohibitive) to have to install an earlier version of Python for that.

If #147 works I may be able to fix this by building wheels for 3.9.

[b0g3r]

@gvanrossum Just to clarify, #147 will add wheels only for windows? As I see on pypi typed-ast also doesn't have wheels for py3.9 manylinux and it unfortunately blocked our migration to 3.9 😢. Maybe while appveyor fixes appveyor/ci#3541 (it can take a few weeks), typed-ast's CI/CD can build linux wheels and publish it?

But I'm not sure what to do with a release process of typed-ast, looks like it'll require two releases (one for manylinux, and one for win) and it will be easier to just little wait.

So, It would be great if typed-ast publish linux wheels, but I understand with respect if you decide to do it in one batch.

Have any problem with install black: psf/black#1744 on latest Windows 10 64-bit.

Microsoft Visual C++ 14.0 Build installed.

Use PyCharm 2020.2 with Python 3.9 from chocolatey: https://chocolatey.org/packages/python3/3.9.0

#147 is green now, so windows users can download prebuilt cp39-win32 and cp39-win_amd64 wheels and install them locally via pip install path\to\typed_ast-1.4.1-cp39-cp39-win*.whl. Still, it would be awesome if @ddfisher, @gvanrossum, @JukkaL or @msullivan can publish those wheels to PyPI to ease the pain.

[JelleZijlstra]

1.4 is old. Please use the latest version.

[daichigb]

I do have the same error as @th-520 on a MAC M1... I can't really upgrade atm for dependencies reason.

[JelleZijlstra]

You'll have to find a way to upgrade. If you're using an old version of mypy that requires typed_ast<1.5, you should be able to just use the latest version of typed-ast and ignore the dependency mismatch. I don't think typed-ast has made any incompatible changes.
