我沒有寫 inputenc 兩次。至少我的主 tex 檔案中沒有它。我不確定是什麼原因導致此錯誤，並且可以使用一些幫助來排除故障。
這是我在文件開始之前寫的所有內容：

這是我收到的錯誤：
LaTeX Error: Option clash for package inputenc.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.2 \usepackage
[british,UKenglish]{babel}
The package inputenc has already been loaded with options:
[utf8]
There has now been an attempt to load it with options
[utf8x]
Adding the global options:
utf8,utf8x
to your \documentclass declaration may fix this.
Try typing <return> to proceed.

所以我把範圍縮小到這一行。回滾到專案運行時並慢慢添加回更改後，這是導致程式碼無法編譯的行。

答案1
您的文檔程式碼有幾個常見問題：
載入
hyperref包最後的。有很少此規則的例外情況。 （該cleveref套件是這些例外之一：它必須在 後加載hyperref。）不要同時加載
subfig和subcaption。它們互不相容。只選其一，但不是兩者都。指令
\lstset{frame=, basicstyle={\footnotesize\ttfamily}有故障。除了必須載入
listings套件（您的程式碼無法執行的操作）之外，為了啟動\lstset宏，指令應該是\lstset{frame=, basicstyle={\footnotesize\ttfamily}}讓它發揮作用。您看得出來差別嗎？
不要
\bf在 LaTeX 文件中使用 Plain-TeX 指令。代替使用\bfseries。不要不必要地使用
{and}——它只會造成程式碼混亂。因此，代替\begin{center} {\large\bf{Abstract}} \end{center}寫吧
\begin{center} \large\bf Abstract \end{center}或者，更好的是，
\begin{center} \large\bfseries Abstract \end{center}請檢查您是否確實需要加載所有這些包。我不禁產生這樣的印象：其中一些內容正在無緣無故地被加載。
實施上述建議後，得到的輸出如下：
