Cannot run Jupyter Notebook on Ubuntu 22.04
问题
我有Ubuntu 22.04，安装了Python 3.10。当我尝试从终端打开Jupyter Notebook时，出现以下错误：
Traceback (most recent call last):
File "/home/anaconda3/lib/python3.10/site-packages/notebook/services/sessions/sessionmanager.py", line 9, in <module>
import sqlite3
File "/home/anaconda3/lib/python3.10/sqlite3/__init__.py", line 57, in <module>

from _sqlite3 import *
ImportError: /home/anaconda3/lib/python3.10/lib-dynload/_sqlite3.cpython-310-x86_64-linux-gnu.so: undefined symbol: sqlite3_trace_v2
During handling of the above exception, another exception occurred:

from pysqlite2 import dbapi2 as sqlite3
ModuleNotFoundError: No module named 'pysqlite2'
当我检查sqlite3时，它安装在home/anaconda3/lib/python3.10/sqlite3/目录下，并包含dbapi2.py。我应该如何重新组织文件夹？ PS：当我尝试执行pip install pysqlite2时，另一个错误发生：ERROR: Could not find a version that satisfies the requirement pysqlite2 (from versions: none) ERROR: No matching distribution found for pysqlite2。

When I checked sqlite3, it is intalled in home/anaconda3/lib/python3.10/sqlite3/ and it contains dbapi2.py. Should I somehow reorganize the folders?
PS: When I tried pip install pysqlite2 another error occurred: ERROR: Could not find a version that satisfies the requirement pysqlite2 (from versions: none)

It looks like you performed a manual installation of Jupyter (and required dependencies) directly in your home directory.
我看起来你在你的主目录中手动安装了Jupyter（以及所需的依赖项）。
I'm assuming /home/anaconda3/ is your home directory, and anaconda3 is just a badly chosen name.
我假设/home/anaconda3/是你的主目录，而anaconda3只是一个选择不当的名称。
Rename the lib subdirectory:
重命名lib子目录：
mv lib lib_aside
You might want to do something similar for include/ or bin/ directories directly in your home as well (but check first what is in bin/ ; if that is all Python/Jupyter related, or that there's software you actually need that is not default installable).
您可能还想在主目录中直接对include/或bin/目录执行类似的操作（但首先检查bin/中的内容；如果那些都与Python/Jupyter相关，或者有您实际需要但不是默认可安装的软件）。
Comment out any PYTHONPATH setting in your .bashrc that points to that lib/ directory (and subdirectories).
在.bashrc中注释掉任何指向lib/目录（以及其子目录）的PYTHONPATH设置。
Comment out any PATH alteration to the bin/ in your home directory as well.
同样，在主目录中注释掉对bin/的任何PATH更改。
If you don't need it, comment-out the section with Conda stuff as well.
如果不需要，同样注释掉包含Conda内容的部分。
Install Jupyter from your package manager. E.g.
从包管理器中安装Jupyter。例如：
sudo apt install python3-notebook
Start a new terminal, and test:
打开一个新的终端并进行测试：
which python
which jupyter
These should point to /usr/bin
这些应该指向/usr/bin
Start your notebook:
启动你的笔记本：
jupyter notebook
