我刚刚在我的笔记本电脑（Ubuntu 20.04）上安装了 Python 3.10。

在 VS Code 中运行 Jupyter Notebook 适用于 Python 3.9，但不适用于 Python 3.10。我收到错误消息：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（请参阅接受的答案）。

我尝试过的事情：

  • 点击重新安装，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（从这个线程）。

  • 正如评论中所问的，这是我单击“重新安装”按钮时的输出：

  • 这是我的_vendor文件夹包含的内容：
joris@joris-N751JK:~$ ls /usr/lib/python3/dist-packages/pip/_vendor/
__init__.py  __pycache__
  • 这是重新安装 pip 并检查_vendor文件的输出：
joris@joris-N751JK:~$ python3 -m pip install --upgrade --force-reinstall pip

我不认为 ipykernel 与 3.10 兼容。

以下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或其他库创建虚拟环境。

为了让你开始：

  1. 安装蟒蛇。
  2. 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

我想为此添加一条评论：

您的解决方案是正确的，但是当我在我的新 Linux 上使用它时它对我不起作用。我做了以下工作来解决这个问题。

可能是使用以下评论后的人：

python3.10 -m pip install ipykernel

'distutils.util' 会出错。所以你应该先安装：

sudo apt-get install python3.10-distutils

然后再次如果您尝试安装，您将收到另一个错误：

ImportError：无法从“pip._vendor”导入名称“html5lib”（/usr/lib/python3/dist-packages/pip/_vendor/

要解决它，您应该使用：

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

最后，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

我终于发现出了什么问题。我在 Python 编码方面相当有经验，但在一般的版本处理方面仍远非专业人士。
这里的问题是ipykernel需要为您安装的每个新 Python 版本重新安装。因此，解决我的问题的方法很简单：

python3.10 -m pip install ipykernel
