我正在使用 auctex，但在 emacs 中预览公式对我来说不起作用。问题似乎与 ghostscript 有关。我尝试使用 brew 重新安装 ghostscript，但出现以下错误。
brew reinstall ghostscript

我使用 brew doctor 并获取所有损坏的符号链接的列表。
在此列表中，您将找到 /usr/local/share/ghostscript/9.10/Resource/Font/logo10.pfb 和其他一些类似的。
然后使用sudo rm '/usr/local/share/ghostscript/9.10/Resource/Font/logo10.pfb'它将其删除。
也许同一目录中有多个，因此您可以使用sudo rm -r '/usr/local/share/ghostscript/9.10/Resource/Font'。
也许这会有所帮助。
