我刚刚在我的笔记本电脑上安装了Python 3.10（Ubuntu 20.04）。
在VS Code中运行Jupyter Notebook适用于Python 3.9，但不适用于Python 3.10。我得到错误消息：Running cells with 'Python 3.10.0 64 bit' requires ipykernel installed or requires an update。

这是一个愚蠢的错误，我解决了我的问题（见accepted answer）。

我尝试的事情：

单击重新安装，运行：

/usr/bin/python3.10 /home/joris/.vscode/extensions/ms-python.python-2021.10.1365161279/pythonFiles/shell_exec.py /usr/bin/python3.10 -m pip install -U --force-reinstall ipykernel /tmp/tmp-12568krFMIDJVy4jp.log

运行pip3 install --upgrade ipykernel jupyter notebook pyzmq（从this线程）。

编辑

正如在评论中所问的，这是当我单击“重新安装”按钮时的输出：

以下是我的_vendor文件夹包含的内容：

以下是重新安装pip并检查_vendor文件的输出：

我想对此补充一点意见：
你的解决方案是正确的，但当我在我的新Linux上使用它时，它对我不起作用。我做了下面的工作来解决这个问题。
大概人们在使用以下评论后：

python3.10 -m pip install ipykernel

将得到'distutils. util'的错误。所以你应该先安装：

sudo apt-get install python3.10-distutils

如果你尝试安装，你会得到另一个错误：
ImportError：无法从'pip._vendor'导入名称'html5 lib'（/usr/lib/python3/dist-packages/pip/_vendor/
要解决这个问题，你应该用途：

curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10

最后，你最好运行：

/bin/python3.10 ~/.vscode/extensions/ms-python.python-2022.0.1786462952/pythonFiles/shell_exec.py /bin/python3.10 -m pip install -U notebook /tmp/tmp-5290PWIe78U4HgLu.log

MacOs M1

python -m pip install jupyter notebook -U

使用这个并重新启动VSCode它可以工作。
如果你看到这个错误也可以工作

Failed to start the Kernel. 

The 'python3912jvsc74a57bd0f40663dfee16db09be6af2ff2550db36bd5354ec153147c40353828514dedb99' kernel is not available. Please pick another suitable kernel instead, or install that kernel. 

View Jupyter log for further details.

几天前它还工作得很好，但是好吧，这个解决了！

我不认为ipycernel与3.10兼容。
下面是我尝试使用以下命令安装ipykernel时收到的消息：conda install -c anaconda ipykernel

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - ipykernel -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.5,<3.6.0a0|>=3.9,<3.10.0a0']

Your python: python=3.10

解决方案：

我建议使用conda或其他library创建virtual environment。
让你开始：
1.安装Anaconda。
1.输入以下命令。[注意：这些是Windows命令-在Mac和Linux上可能略有不同。]

# Create virtual environment
# Use a version of Python that is less than 3.10
conda create --name your_env_name python<3.10

# Activate new environment
conda activate your_env_name

# Install ipykernel
conda install -c anaconda ipykernel

# Add this new environment to your Jupyter Notebook kernel list
ipython kernel install --name your_env_name --user

# Windows only: When trying to launch `jupyter notebook`, you may receive a win32api error.
# The command below fixes that issue.
conda install -c anaconda pywin32

我终于发现了哪里出了问题。我对Python编码相当有经验，但在一般的版本处理方面仍然远远不是专业人士。
这里的问题是，ipykernel需要为每个新的Python版本重新安装。因此，解决我的问题的方法很简单：
