在 XeTeX 遇到一些问题后，我决定开始尝试 LuaTeX。不幸的是，我遇到了一个无法立即解决的问题。
我确实需要 CJK 支持。根据一些快速研究，在 LuaTex 中实现此目的的方法是使用luatexja包。但是，每当我将这个包与 KOMA 脚本文档类（到目前为止我已经广泛使用）一起使用时，它都会抛出以下相当烦人的警告：
LaTeX Warning: Command \selectfont has changed.
Check if current package is valid.
它之所以令人讨厌是因为它会导致 vimlatex-suite关闭我正在处理的文件并打开lltjfont.sty（根据其路径，它似乎是 的一个补丁luatexja）进行检查。
无论我是否实际使用该包执行了什么操作，只要包含该包就会抛出错误。对于 MWE：
\documentclass{scrartcl}
% luatexja-fontenc also includes fontenc for use in
% conjunction. However the warning is thrown with just
% luatexja as well, so fontenc doesn't seem to be the
% problem
\usepackage{luatexja-fontenc}
\begin{document}
Dummy text
\end{document}
你们知道如何解决冲突吗（或者至少由于文档编译正常，可以消除警告）？
顺便说一句，我在 TexLive2018 上。我的\listfiles输出：

如果您使用 vim，则可以自定义其在出现警告和错误时的反应。请参阅此处——http://vim-latex.sourceforge.net/documentation/latex-suite/compiler-output-customization.html——关于适应的方式，但是，关于编译 LaTeX 的整个部分似乎值得一读：http://vim-latex.sourceforge.net/documentation/latex-suite/latex-compiling.html
重点是：每次编译时你都会收到一堆警告，因此花时间和精力来定制 vim 确实是值得的。
