For those not following the GitHub issue, I managed to reproduce the problem: https://github.com/sagemath/sage-windows/issues/42#issuecomment-580268035 As far as I can tell it has nothing to do with virus scanners, and instead impacts users of the texlive LaTeX distribution for Windows. I was previously using MiKTeX, which for some reason does not exhibit the same problem. A workaround, pending a better solution, is to remove texlive from your $PATH environment variable when running Sage. It shouldn't be necessary to do this every time, I don't think. Just once so that matplotlib can regenerate its font cache. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
