Cannot install jamspell on macOS Big Sur via pip?

I followed the instructions on how to install JamSpell spell checking library.
I installed swig by running brew install swig (v. 4.0.2), but I cannot manage to install the library with pip install jamspell on macOS Big Sur, Python3 (not even with sudo).

What is going on here?

Having encountered this same exact problem with your same desktop specs, this thread should fix your problem. It took a long while for me to find this buried discussion, but since your post came up at the very top of my original search results, I'm hoping that keeping this up can guide other people to a solution much more quickly.
I'm linking it here but also including the solution that worked for me:
Manually download swig3 via sourceforge
Extract the zipped download folder
Run the following via terminal:
Downloads/swig-3.0.12/configure && make && make install
Running this command will display a very long output and take ~1 minute
Run pip install jamspell
Terminal may appear to "hesitate" for a second longer than it would with the normal installation process before building wheels for the package:
It'll tell you the package has been installed, but you will not see the usual:
Downloading jamspell-0.0.12.tar.gz (174 kB) |████████████████████████████████| 174 kB 4.1 MB/s
An alternative is, if you just run the package via Co-Lab, it'll work. The only downside I suppose is that you'll have to reinstall the package every time you reconnect.

Notice that in the output that "CMake must be installed to build the following extensions: dlib". So install CMake first and only then try to install dlib. If CMake is installed, try updating your pip version to 21.1.2 via "D:\Install Drive\python.exe -m pip install --upgrade pip".

It requires cmake must be installed before installing dlib. Do execute in the following order.
pip install cmake
pip install dlib
This will fix the issue.

Python 2.7 - error installing MySQL-Python on Windows 8

I have been beating my head against a wall on this for 2+ days and am making no progress.
I am trying to install the Python MySQL connectors on my Windows 8 (hate Windows 8) box.
I am using Python 2.7. I originally received an error:
vcvarsall.bat is not found.
I did some research and found that I needed VS 2008 (VC++ compiler) installed on my box and I installed the express version. I also added ProductDir value with the path to vcvarsall.bat to the following key in my registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\Setup\VC.
I also added the VS90COMNTOOLS environment variable with the path to vcvarsall.bat. I am still getting an error when I run the following:
pip install MySQL-python
Any input you can provide is most appreciated... Thanks...
The error is listed in the following snippet from the pip.log:

The pip install failure suggests there is some underlying dependency on compiled files. An alternative would be to use the .exe installer from https://pypi.python.org/pypi/MySQL-python - but this isn't suitable for virtualenvs, and will fail for 64-bit Python (it will complain that it can't find Python 2.7 in the registry even though it is installed).
Luckily, Christoph Gohlke maintains some unofficial Windows binaries which are pip-installable. You can find them at at http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
You can now call pip install C:/PATH/TO/MySQL_python‑1.2.5‑cp27‑none‑win_amd64.whl from your main Python environment, or a virtualenv.
Ideally, wheels like these will be made available via the MySQL-python PyPI page, at which point a simple pip install will work.
(This answer is based on Carsten's helpful comments.)
