Question

刚刚安装了jupyter笔记本，当我运行jupyter笔记本时说：

jupyter notebook Error executing Jupyter command 'notebook': [Errno 2] No such file or directory

所以试图检查哪些命令存在，它说：

jupyter --help 
... 
Available subcommands: kernel kernelspec migrate run troubleshoot trust

所以没有笔记本命令？所以我试过了：

jupyter run

它没有失败，但不确定在localhost上访问哪个端口：8888什么都没有..你怎么看？我做错了什么？

更新：有关我使用的命令和环境的更多信息：

Answer 1

我在Linux Mint 19中遇到了同样的问题。

只需在终端中输入以下内容

sudo apt install jupyter-notebook

然后输入jupyter-notebook 完成。

Answer 2

我遇到了类似的问题。这就是我为解决这个问题所做的工作（在Ubuntu 16.04上）：

sudo apt-get remove ipython

sudo apt-get purge ipython

sudo apt-get autoremove

pip install jupyter

ipython似乎是问题，因此删除它解决了问题。

我现在可以运行jupyter notebook

了

Answer 3

安装了anaconda：https://anaconda.com，现在jupyter notebook启动没有问题。

jupyter notebook执行Jupyter命令时出错＆＃39; notebook＆＃39;：[Errno 2]没有这样的文件或目录
