[issue40632] AttributeError: type object 'Callable' has no attribute '_abc_registry'

[Ivan Levkivskyi]

Ivan Levkivskyi  added the comment:

I think a better question is why the `typing` in site packages is ever 
imported? I thought that an stdlib module always takes precedence over an 
installed one with the same name.

[issue40632] AttributeError: type object 'Callable' has no attribute '_abc_registry'

[Дилян Палаузов]

I used python 3.6, I exported all dependencies with `pip list`, then upgraded 
to python 3.8 and imported the exported dependencies.

Uninstalling the “typing” module has helped.

Do you mean, that python 3.8 includes the “typing” modules, so that it may not 
be re-installed over pip?

Why pip does not prevent the user from installing the “typing” modules on 
python 3.8?

You seem to use typing backport that has this issue :

[issue40632] AttributeError: type object 'Callable' has no attribute '_abc_registry'

[Дилян Палаузов]

New submission from Дилян Палаузов :

I have the newest cpython 3.8 (07bd5cf3d9551ae), installed with `./configure 
--enable-loadable-sqlite-extensions --disable-ipv6 --with-system-expat 
--with-system-libmpdec --enable-shared && make && make install`.

Calling `pip-20.1 install -U meson` prints:
