LaTex的安装并不需要管理员权限 > You do not need to be root (administrator on Windows) to install, use, or manage TeX Live. Indeed, we recommend installing it as a normal user, except perhaps on MacOSX, where it's conventional to install as administrator. 下面是Ubuntu的安装方法 第一步: 下载ISO文件(清华镜像源) 下载地址: [https://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/Images/texlive2020-20200406.iso](https://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/Images/texlive2020-20200406.iso) > 其他镜像站点，可以在 [https://ctan.org/mirrors](https://ctan.org/mirrors) 进行选择 第二步: 在Windows上解压缩ISO文件，然后上传到服务器, 我们假设上传到家目录下的texlive 第三步: 运行安装命令 ```Bash cd texlive perl install-t ``` 输出信息如下 ```Bash ======================> TeX Live installation procedure <===================== ======> Letters/digits in <angle brackets> indicate <======= ======> menu items for actions or customizations <======= Detected platform: GNU/Linux on x86_64 <B> set binary platforms: 1 out of 6 <S> set installation scheme: scheme-full <C> set installation collections: 40 collections out of 41, disk space required: 6516 MB <D> set directories: TEXDIR (the main TeX directory): !! default location: /usr/local/texlive/2020 !! is not writable or not allowed, please select a different one!

Add /home/xzg/opt/texlive/texmf-dist/doc/info to INFOPATH. Most importantly, add /home/xzg/opt/texlive/bin/x86_64-linux to your PATH for current and future sessions. Logfile: /home/xzg/opt/texlive/install-tl.log ``` 即在 `~/.bashrc` 或 `~/.zshrc` 这些配置文件下添加如下内容 ```Bash export MANPATH=$MANPATH:/home/xzg/opt/texlive/texmf-dist/doc/man export INFOPATH=$INFOPATH:/home/xzg/opt/texlive/texmf-dist/doc/info export PATH=$PATH:/home/xzg/opt/texlive/bin/x86_64-linux ```
