sdl2 - TypeError: expected bytes, str found

[Michael Ebstyne]

I'm having issues with new sdl2 provider for Windows. I'm hoping someone can point me in the right direction.

Repro:

1. Download Python 3.4.

2. Download Kivy‑1.9.0+sdl2‑cp34‑none‑win32.whl (from gohlke)

3. pip install Kivy‑1.9.0+sdl2‑cp34‑none‑win32.whl

4. Run:

class MyApp(App):
    def build(self):
        return Button(text='Hello World')

MyApp().run()

Output:

I know gohlke distribution is "unofficial" that said... it's popular. I'm wondering what I'm missing?

Thanks,

Its most likely related to the build process used there.  According to the following, this particular issue is caused when the python2 build is done first, followed by the python3 build, without clearing the build files from the python2 build first.  The solution seems to change the build process used by gohlke.
