我正在尝试安装 mathrsfs 字体包。我按照说明进行操作这里我正在使用 Anki 编译 LaTeX。我尝试通过在所有其他 \usepackage 命令所在的位置键入 \usepackage{mathrsfs} 来加载包，但是当我尝试编译文档（在本例中是闪存卡，因为它是 Anki）时，即使该卡不涉及 \mathrsfs 命令，我也会收到错误：

我正在将 mathrsfs.rme 和 mathrsfs.sty 文件复制到名为“base”的文件夹中，地址为：
在 /usr/local/texlive/2019basic/texmf-dist/tex/latex
当我下载 mathrsfs 包时，我得到了一个名为 jknappen 的文件夹，里面有一堆文件，似乎与其他包相对应，但我只对 mathrsfs 感兴趣，所以我把这两个文件拉了出来。
当我在终端上运行“哪个乳胶”时，我得到
/图书馆/TeX/texbin/latex
我能做些什么？
PS 我尝试运行“tlmgr install mathrsfs”，但出现错误，提示远程存储库是 2020 版本，与我的 2019 LaTeX 不兼容。我可以尝试简单地更新我的 LaTeX，但我不知道是否有万无一失的方法，我担心安装失败并毁掉一切。
