RuntimeError: Overloading is only supported in library stubs

[joongh]

I got an exception when I simply imported the module right after the installation of the module through pip.
Here is the whole error messages.

Could you try installing the latest typing library from PyPI?

[joongh]

Here is the modules installed on my environment.

joong$ pip freeze
Babel==2.5.3
prices==1.0.0
pytz==2018.3
typing==3.6.4

[patrys]

I see, typing==3.6.4 has no effect in Python 3.5 which still falls back to the builtin typing==3.5.x that does not support overloading in Python code. As a workaround I suggest upgrading to Python 3.6 but we may be forced to find a better fix for the long run.

OK, I understood. I hope you fix it soon.
Thank you for your quick response.
