python - 安装后无法在 ubuntu 18.04.3 上启动 jupyter notebook

问题描述

我正在使用 python3 并且我安装了 jupyter-notebook 运行： $ sudo apt install jupyter-notebook

现在，当我输入“jupyter-notebook”时开始出现以下错误：

Traceback (most recent call last):
  File "/usr/bin/jupyter-notebook", line 11, in <module>
    load_entry_point('notebook==5.2.2', 'console_scripts', 'jupyter-notebook')()

解决方案

我使用 pip解决了这个安装/更新库pyzmq的问题：

pip3 install pyzmq

注意：仅pip在您使用 Python2 时使用。

如果您正在使用conda，则可以运行：

conda install -c anaconda pyzmq
