在Latex中标题之前不需要的空白页

Question

在Latex中的标题之前有一个不需要的空白页，我不明白为什么这个空白页中有字符串"_result_result“，我很确定我没有在这里添加它们是我的代码。**我正在用背页编辑并使用LuaLaTex **

不需要的空白页

Answer 1

请不要忽略.log文件中的错误和警告。它们准确地告诉您，您的包中哪个是不兼容的，哪些命令丢失了。

总结这些变化：

• 很多不兼容的包
• \titleformat中的语法错误。特别是你不能写\titleformat{}{}
• 编写\textbf some text是错误的。它是一个宏，所以要么需要\textbf{some text}，要么需要\bfseries some text。
• 您应该清理您的序言，许多包是多余的，没有任何意义，或加载了多次。
