Latex 错误：未找到文件“scrlayer-scrpage.sty”

Question

整个代码中存在 TeX 编辑器（使用 TeXstudio）的“不可见”字符，阻止其正确编译。

我打开了 tex 文件notepad++ > View >Show Symbol > Show All Characters

例如看看

â€Ž\addbibresource{example.bib} % The filename of the bibliographyâ€Ž

第一个â€ž是不应该存在的 UTF-8 字符！

从https://www.i18nqa.com/debug/utf8-debug.html

U+201E 0x84 „ â€ž %E2 %80 %9E

清理文件后（再次使用 notepad++），它可以编译并且不会出现错误。

这是清理后的代码

更新

我只能! LaTeX Error: File scrlayer-scrpagex.sty not found.通过将文件的第 278 行从更改MastersDoctoralThesis.cls 为来重现该错误\RequirePackage[markcase=used]{scrlayer-scrpage}，例如\RequirePackage[markcase=used]{scrlayer-scrpagex}。

我猜你使用的文件不知何故损坏了。从https://www.latextemplates.com/templates/theses/1/thesis_1.zip
