我尝试在jupyter notebook（python版本3.8.13，matlab 2020 b）中运行以下代码

import matlab.engine   
eng=matlab.engine.start_matlab()

首先，它给了我matlab的模块找不到错误。所以，我在命令提示符下执行these instructions，这就是结果（更多错误）。我不确定下一步该怎么做-还没有在网上看到类似的错误。有人建议下一步该怎么做吗？谢谢。

这是我在阅读错误后尝试的两件事：

(research_projects) C:\Program Files\MATLAB\R2020b\extern\engines\python>python3 -m pip install --prefix="c:\users\user\anaconda3\envs\research_projects"
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.

ERROR: You must give at least one requirement to install (see "pip help install")

(research_projects) C:\Program Files\MATLAB\R2020b\extern\engines\python>

然后，我尝试了以下操作（降级setup.py）

(research_projects) C:\Program Files\MATLAB\R2020b\extern\engines\python>pip install setuptools==58.2.0
Collecting setuptools==58.2.0

UPDATE所以在最后一步之后，我只是以管理员的身份运行cmd并重试pythonsetup.py提示符，它工作了！
