Cannot install jamspell on macOS Big Sur via pip?

Question

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?

Answer 1

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:

1. Manually download swig3 via sourceforge
2. Extract the zipped download folder
3. Run the following via terminal:
   <add_directory_of_folder_here>/swig-3.0.12/configure && make && make install
   • Running this command will display a very long output and take ~1 minute
4. 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 install, 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.
