我正在 Overleaf 上寫我的博士論文，我使用的是我在網路上找到的模板，並根據我的大學指導方針進行了調整。我對 LaTeX 非常陌生，並且是一個基本用戶。
大約一個月前，我一直無法在 Overleaf 上編譯我的論文，儘管沒有顯示錯誤。因此，我將 LaTeX 下載到 Mac 上，但當我嘗試編譯該文件時，收到此錯誤訊息：Argument of \blx@defformat@i has an extra }請參考第 92 行（我修改了參考書目設置，使其符合我的大學指南）。
這是我的序言的一部分：

答案1
標記前的線%here error while compiling有故障。
\DeclareFieldFormat[misc]
根本就是不完整的。的語法\DeclareFieldFormat是
\DeclareFieldFormat[<entry type_1,...,entry type_n>]{<field>}{<formatting code>}
有問題的行缺少兩個強制參數。我無法猜測這兩個參數應該是什麼，所以為了讓這個錯誤消失，我建議你刪除這一行。
請注意，即使 Overleaf 產生了 PDF 輸出，Overleaf 也應該向您顯示該錯誤行的錯誤。
確實如果我嘗試
\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=authoryear]{biblatex}
\DeclareFieldFormat[misc]
\addbibresource{biblatex-examples.bib}
\begin{document}
Lorem \autocite{sigfridsson}
\printbibliography
\end{document}
如https://www.overleaf.com/read/rvgqqbfngrrv
我收到 Overleaf 報告的一個錯誤（請參閱“重新編譯”按鈕旁邊帶有 1 的紅色框 - 以粉紅色突出顯示）
Overleaf 可以很好地向您隱藏錯誤訊息。這就是為什麼你應該總是確保您的文件沒有錯誤。也可以看看Overleaf 用戶沒有註意到錯誤訊息的範例。
