自 MacTeX 2021 升级以来，包含 PStricks 代码的文档不再像以前在配备 M1 芯片的 Mac 上使用以前的 MacTeX 2020 发行版那样进行编译。更准确地说：我确实获得了 pdf 输出，但 pspicture 区域是空白的，以及其后编码的所有内容（所有内容都出现在 pspicture 上方）。
问题是，一旦我隐藏代码（pspicture 部分），文档就会顺利编译。
我尝试恢复到 2020 发行版，没有任何问题......
这是在 2021 升级之前可以使用的代码：
\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{pstricks}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\begin{document}
Ceci est un essai.
\medskip
\psset{xunit=1cm,yunit=1cm}
\begin{pspicture}(0,0)(10,5)
\psline(0,0)(10,5)
\end{pspicture}
\end{document}

我一直在寻找解决方案，但没有成功。我的想法是，由于除了 2021 升级之外我没有做任何更改，所以问题出在新发行版中，它将在下一次更新中很快得到解决。
我希望你们中的一些人能给我一些帮助。那就太好了。
非常感谢并致以最诚挚的问候。
答案1
MacTeX-2021 安装了 Ghostscript 9.53.3，而 pstricks 想要创建透明背景，而 ps2pdf 默认不再允许这样做。您必须将标志添加-dAllOWPSTRANSPARENCY到 ps2pdf 运行中。如果您使用的是 TeXShop，您可以选择允许这样做的引擎：从我的下载网站获取它们GhostscriptTransparencyEngines.zip，<https://herbs.github.io>. 安装说明随发动机一起提供。
