我正在使用 jupyter notebook，用 latex 写一些作业。最近，我在尝试从量子力学（bra、ket）中写入符号时遇到了一个问题。
当我在 markdown 单元格中写入以下内容时：$\bar{\psi}$ 。它无法识别 \bra。我想我应该为此安装一些包，但我不知道如何去做。
最终我找到了这个地点有关为 jupyter notebook 安装一些乳胶环境的说明，但我不确定它是否包含物理包，而且我实际上未能安装它。
这是输入时终端的读数
pip3 install jupyter_latex_envs [--user][--upgrade]

这是我尝试通过 pip 安装后出现的错误。
所以底线是，我想学习如何将物理乳胶包加载到 jupyter 笔记本中，如果我当前的尝试确实是好的，那么我想学习如何传递当前的安装错误。
