[OS X TeX] How to get xasy to run?

Thu Aug 20 18:43:54 EDT 2020

I get the same error on Catalina, I don’t have the Qt bindings. Presumably running ‘pip install PyQt5’ will take care of that. 

As for Murray’s error I don’t know: there’s an anaconda installed python3. How was it installed?

If you already use Macports, this will probably be a simple matter to do a "port install." (Using Macports is one of the recommended approaches for OS X given on the Asymptote site. The other is compiling from source, which could be a daunting procedure.)

That executable seems to be asy in /Library/TeX/texbin (actually, tracing the link, in /usr/local/texlive/2020/bin/x86_64-darwin). And I can get that to work with the TeXShop Asymptote engine.
