这是后续问题forest tex 容量超出 [保存大小=50000]它收到两个答案。两者都解决了 op 问题，并建议将 oplatex分布升级为texlive 2018。
我使用最近的（昨天升级的）测试了这个（巨大的）森林示例miktex并收到类似的错误：
! TeX capacity exceeded, sorry [save size=50000].
\pgf@process #1->{
#1\global \pgf@x =\pgf@x \global \pgf@y =\pgf@y }
l.982 \end{forest}
If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

如何说服miktex编译这个forest tex 容量超出 [保存大小=80000]文档没有错误吗？

可以增加 MiKTeX 中的值
对于 PdfLaTeX，您可以通过在编辑器中添加附加选项来更改运行时编译值，例如
pdfLaTeX -save-size=80000 其他选项如 -shell-escape 或 -synctex=...
但是我无法在我的编辑器 LuaLaTeX 命令行上使用相同的临时设置
我必须导航到我的配置文件夹，并且每个用户的配置都会有所
不同不是texmfs\安装\miktex\配置
我使用便携式安装，所以对我来说
它位于 texmfs\config\miktex\config请注意，您的系统中存在多个与 LuaLaTeX.ini 同名的文件。
它应该位于包含大约十几个文件的文件夹中
控制台.ini 格式.ini 语言.ini ... ... yap.ini
如果您没有名为 lualatex.ini 的文件，请添加它（如果它包含大量内容，则可能是错误的，因此请检查相邻的文件）
如果您满意它是正确的位置，那么添加此行save_size=1000000
，编译现在就可以工作了，对我来说确实如此。
PS 请耐心等待，由于数据量太大，编译过程中确实会暂停几分钟
