這是後續問題超出森林 tex 容量 [保存大小=50000]收到兩個答案。兩者都解決了 op 問題，並建議將 oplatex分發升級到texlive 2018.
我用最近的（昨天升級的）測試這個（龐大的）森林範例miktex並收到類似的錯誤：
! 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.
Here is how much of LuaTeX's memory you used:
85529 strings out of 494300
244514,1373583 words of node,token memory allocated 204422 words of node memory still in use:

如何說服miktex編譯這個超出森林 tex 容量 [保存大小=80000]文檔沒有錯誤？

可以增加 MiKTeX 中的值
對於 PdfLaTeX，您可以透過在編輯器中新增附加選項來變更執行時間編譯值，例如
pdfLaTeX -save-size=80000 其他選項，例如 -shell-escape 或 -synctex= ...
但是我無法在編輯器 LuaLaTeX 命令列上使用相同的臨時設定
我必須導航到我的配置資料夾，每個使用者的配置資料夾都會有所
不同不是其中之一texmfs\安裝\miktex\config
我使用便攜式安裝，所以對我來說
它位於 texmfs\config\miktex\config請注意，您的系統中散佈著多個同名 LuaLaTeX.ini 的檔案。
它應該在包含大約十幾個文件的資料夾中
console.ini 格式.ini 語言.ini ... ... yap.ini
如果您沒有名為 lualatex.ini 的文件，請添加它（如果它有很多內容，則可能是錯誤的，因此請檢查相鄰文件）
如果您很高興這是正確的位置，那麼添加這一行save_size=1000000
，編譯現在應該可以工作，它對我來說是這樣。
PS請耐心等待，由於資料量較大，編譯過程中會暫停幾分鐘
