我在 Pi 4 上安装了 Jupyter Notebook，最初它工作正常，但现在它给出 500：INTERNAL SERVER ERROR。所以，我尝试用 conda 安装，然后我安装了 Miniconda。当我尝试使用 conda 安装 Notebook 时，会出现以下错误：
pi@raspberrypi:~ $ conda install notebook
Fetching package metadata: ......
Solving package specifications: ..
Error: Unsatisfiable package specifications.

Hint: the following packages conflict with each other:
- notebook
- python 3.4*
Use 'conda info notebook' etc. to see the dependencies for each package.
所以我尝试了 conda info notebook 它给出了以下内容：
pi@raspberrypi:~ $ conda info notebook
