Failure in 'Looking for ctypes DLLs' when specifying 'ctypes' as a hidden import.

[Viech]

With hiddenimports=["ctypes"], I get the following exception:

On the other hand, when I needlessly import ctypes in my main script, everything works like a charm.

I want to set ctypes as a hidden import because it is required by bearlibterminal, a Python dependency that I add manually to work around #3584.

I'm having this same issue. Project on python 2, getting this exception when importing this module. Anyone knows some workaround ?

@Shincham Python 2 is not supported anymore, and PyInstaller versions that support it are not supported anymore, either. But you can backport and apply the fix from the linked PR to your PyInstaller installation.

Thanks for the reply and for the workaround. I copied your change on the commit to my localfile and it solved my problem. Module was succesfully bundled and also stopped the runtime error.

But it's not possible to include this change in the pyinstaller 3.6 version ? This change will only go to the version 4+ ?

Indeed, it will go only into next release. We don't do multi-version branching and releases.
