我尝试将jupyter notebook与内核python3一起使用,但收到此错误消息。
anonymous$ jupyter notebook

有关在Mac上安装的python和pip的信息(我使用pip3安装jupyter):

试图通过“ brew update && brew upgrade jupyter”解决该问题,如另一篇文章所建议的那样,但是没有用。得到了一条错误消息,指出“错误:未安装jupyter”。
您必须已使用其他软件包管理器(例如)安装了jupyter pip。您可以尝试pip uninstall jupyter使用brew install jupyter。
如果收到消息:
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/jupyter
Target /usr/local/bin/jupyter already exists.

您可以brew link --overwrite jupyter按照建议尝试。

当从可能不再存在的以前的 python 版本加载 jupyter 笔记本的内核时,通常会出现此问题。
jupyter kernelspec list。kernel.json 包含正在使用的 python 版本的路径。您可以直接更改此路径,也可以取消 Jupyter 安装(如下所示)并重新安装。rm -rf /Users/<username>/Library/Jupyter/:)brew uninstall jupyter; brew cleanuppip install jupyterlab否则brew install jupyter
