我对使用 LaTeX 还很陌生，所以请多多包涵 :)
规格：使用 Windows 操作系统、TexLive、Overleaf（最初）。使用可访问的软件包https://libguides.lib.msu.edu/c.php?g=995742&p=8207771
情况：我正在用 LaTeX 开发一个基于数学的可访问性模板。我的 tex 文件是在 Overleaf 上制作的，没有错误。我已将此文件下载为 zip 文件，并将其解压缩，现在正尝试将此 tex 文件转换为 HTML 文件，以便屏幕阅读器可以更轻松地读取它（与 PDF 相比）。我在 Windows 操作系统上使用 TexLive 进行转换。
问题：我在 TexLive 命令行中使用 htlatex LaTeX_Accessible_Template.tex，但没有生成输出文件。我尝试查看日志文件，但在谷歌上搜索警告/错误却无济于事。
问题：有人能帮我解读日志文件并找出我做错的地方吗？我已将模板和日志文件都包含在下面的 Google Drive 中：
我认为主要问题在于日志文件中的以下几行：
! pdfTeX error (\pdfobj): not allowed in DVI mode (\pdfoutput <= 0).
<recently read> \pdfobj
l.68 \pdfobj
reserveobjnum%
No pages of output.

答案1
正如 Ulrike 所说，这个accessibility软件包才是罪魁祸首。它明确使用了一些 PDFTeX 原语，导致 TeX4ht 使用的 DVI 模式下的 LaTeX 出现致命错误。
这是一个可以防止此致命错误的配置。它有点复杂，所以你可能需要等到 TeX Live 中包含修复程序，这应该很快就会实现。
我们需要多个配置文件才能使其工作。首先是usepackage.4ht：

此文件声明了应在 LaTeX 包之前加载的配置文件。可访问性的配置文件accessibility-hooks.4ht如下所示：

最后一个必需的文件是accessibility.4ht，我们可以在其中重新定义文档中使用的命令。在本例中，\alt使用的是：

\NewConfigure{accessibilityalt}{2}
\def\:tempa#1{\a:accessibilityalt #1\b:accessibilityalt}
\def\alt#1{}
\HLet\alt\:tempa
\Hinput{accessibility}
\endinput
此重新定义的版本\alt将在文档文本中打印其内容，但不会在图片中显示任何内容。这是为了防止出现其他错误。
