I found some instruction on the site but it was hard for me to follow it since I'm new to this stuff
Thanks in advance
Try to upgrade setuptools wheel
pip install -U setuptools wheel
End then try
pip install cppyy --no-index
If not help, that problem may by with python 3.8
By PyPi it’s supported <=3.7
As shown in the error message and mentioned already by hoefling, you need a system compiler, at the very minimum for system headers, but also for C++ library headers. Cling needs the code from these headers to parse any new C++ code you may give it that uses C++ standard library or Windows system features.
In principle, it's possible to ship a precompiled header with cppyy-cling that contains all system and C++ headers as IR bitcode, but MSVC likes to change header include guards between versions, so that would then only work if there is no system compiler. (It's somewhat better on Linux, but it, too, has changed include guard names in some instances.) This will be revisited once Cling supports precompiled modules (PCMs; as opposed to headers) on Windows. Then these PCMs can be prepackaged and installed conditionally if no system compiler is available. Module support in upstream is, however, still very fresh and not even released yet, so this is something that will only appear in the medium-term.
Anyway, MSVC is free these days. :)

I don't really understand what this means, and I'd like some assistance installing a package and trying to fix this error. Thanks! -Shane

EDIT: I have installed libffi-dev.
Solved by upgrading pip to pip3 using sudo apt-get -y install python3-pip.
Looks like you may need to install libffi-dev. I'm not sure your distro, but it'll be there. Distro is raspbian.
Install with:
apt-get install libffi-dev
There are other questions that looks similar since they have the _ctypes issue, but I won't mark this as a duplicate since your question is exactly the same. I think the underlying root cause is probably the same. See here and here.

I'm not exactly sure about that error, but for Tensorflow in general, if you go to this page, you'll see that, as of this writing, the only supported version of python are 3.6 - 3.8. It sounds like for tensorflow/models, you might do well to use 3.7. You will want to make sure you have a compatible version of pip as well.
I'm following Beeware tutorial and unable to 'briefcase create'.

I believe the main problem is
Requested 'cairo >= 1.15.10' but version of cairo is 1.14.6
But what I don't understand is were is cairo 1.14.6 if I have only cairo 1.20.0 installed.
I tried to update docker, reinstall cairo and pycairo, updated python packages but the error is still there.
The beeware build process is trying to install the pycairo package. This package is just a python interface to the cairo graphics library (libcairo2).
pycairo changelog shows, newest version 1.20.0 for pycairo, which requires cairo (libcairo2) version 1.15.10+.
If you are lucky, you can simply update your cairo package to a version which satisfies the requirement. Info is on the official site cairographics.org/download/.
I have the same problem as you. In my case I am again reminded to upgrade my OS to newer version of Ubuntu, since the cairo package libcairo2 is only available in version 14.6 in Ubuntu 16.04 LTS official PPA. In Ubuntu 20.04 LTS the available libcairo2 is 16.0. I suspect you have a simmilar OS, because your installed cairo version is the same as mine.
You can build the package from source to bypass the error:
