Ubuntu环境下VSCode LaTeX Workshop报错Cannot find LaTeX root file的解决求助

大家好，我最近刚从Windows转到Ubuntu系统，主要是为了学习编程。之前在Windows上用VSCode搭配LaTeX Workshop写LaTeX课程作业一直很顺利，但换到Ubuntu后配置过程中遇到了一堆问题，大部分都磕磕绊绊解决了，唯独最后这个问题卡了好久，实在没办法来求助各位。

问题现象 #

当我尝试编译LaTeX项目时，终端输出如下内容，之后就没有任何反应了：

另外，打开VSCode时的日志里也有相关错误：

我已经尝试过的解决步骤 #

• 按照TeXLive官方文档进行快速安装，在home目录创建了texlive文件夹，执行文档中的命令时，cd install-tl-*命令失败，后来用完整的目录名称才完成这一步
• 尝试更新PATH环境变量，一开始没成功：
  • 参考了其他遇到相同问题的用户方案，试过用tlmgr GUI更新PATH，但执行echo $PATH后还是看不到texlive的路径
  • 按照Ubuntu官方文档关于环境变量的说明，在/etc/profile.d/目录下创建了myenvsvars.sh文件，写入export PATH=$PATH:/usr/local/texlive/2023/bin/x86_64-linux，终于在echo $PATH里看到了texlive的路径，当前PATH内容为：

    /home/alejandro/anaconda3/envs/latex/bin:/home/alejandro/anaconda3/condabin:/usr/local/texlive/2023/bin/x86_64-linux:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
    

• 通过sudo apt install latexmk命令安装了latexmk
• 遇到当前报错后，还尝试给LaTeX Workshop的tools配置手动添加PATH环境变量，我的latex-workshop.latex.tools相关配置如下：

  {
    "command": "latexmk",
    "args": [
      "--shell-escape",
      "-synctex=1",
      "-interaction=nonstopmode",
      "-file-line-error",
      "-pdf",
      "-outdir=%OUTDIR%",
      "%DOC%"
    ],
    "env": {"PATH": "/usr/local/texlive/2023/bin/x86_64-linux:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin"}
  }
  

  但修改后问题依旧，没有任何变化。

我目前使用的是Ubuntu 23.10系统，LaTeX Workshop版本是9.15.0，实在不知道哪里出问题了，希望各位能给我一些建议，非常感谢！
