在org文件中，文件内容如下：
使用org-latex-preview预览latex代码 $a=1$，但报错：
Creating LaTeX preview… org-compile-file: File “c:/Users/ADMINI~1/AppData/Local/Temp/orgtexLY8mon.dvi” wasn’t produced. Please adjust ‘dvipng’ part of ‘org-preview-latex-process-alist’.
org-preview-latex-process-alist的值如下：
((dvipng :programs

在C:\Users\Administrator\AppData\Local\Temp中能找到它自行创建的文件orgtexLY8mon.tex。没有orgtexLY8mon.dvi文件。但是我可以在终端用latex orgtexLY8mon.tex编译出orgtexLY8mon.dvi，再通过dvipng -o orgtexLY8mon.png orgtexLY8mon.dvi得到png文件。说明orgtexLY8mon.tex文件和latex和dvipng都是正常的。而且在emacs中，(executable-find "latex")和(executable-find "dvipng")都能正确返回值
"c:/texlive/2021/bin/win32/latex.exe""c:/texlive/2021/bin/win32/dvipng.exe"
