（这个问题接下来是在Android上安装Latex）
我使用 Termux Android 安装了 texlive 包。使用 VerbTex 我在本地创建了 test.tex 文件。但是当我使用它调用它时。
pdflatex ./test.tex
我没有得到结果。有没有办法使用 Termux 编译 LaTex？

经过对这个问题评论中的建议进行一些研究后，我能够在 Android 上使用 Termux 编译 .tex 文件。所以我想我可以回答我自己的问题，这样未来的访问者就不会感到任何麻烦。
I can't find file 'dehypht-x-2019-04-04.tex'
此问题是由于缺少 texlive 包 langgerman 造成的。因此运行以下命令：
apt install texlive-langgerman
安装此软件包。但我个人建议您安装“texlive-full”，这样就不会出现与软件包相关的问题。您可以通过在 termux 中运行以下命令来执行此操作。
pkg install texlive-full
现在让我们看看编译部分。首先，运行“pdflatex”。这将给出以下输出。
This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Termux) (preloaded format=pdflatex) restricted \write18 enabled.**
** 之后，您必须指定文件位置和文件名。假设您的 file.tex 保存在内部存储>下载中，那么您可以在 Termux 中运行以下命令
/storage/emulated/0/download/file.tex
那么你的编译就成功了。要打开编译好的文档，你可以阅读以下内容：在Android中打开编译后的文档
根据我的理解，我制作了两个视频来说明如何在 Android 上使用 LaTex。你可以在这里查看。
