无法在 Ubuntu 中启动 Jupyter Notebook

Question

上周我更新了 Jupyter 笔记本后，它的启动开始失败。我尝试更新 anaconda、anaconda-navigator 和 updater。这些都不起作用。

错误如下：

Traceback (most recent call last):
  File "/home/charcoalp/anaconda2/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/home/charcoalp/anaconda2/lib/python2.7/site-packages/notebook/notebookapp.py", line 46, in <module>
    from zmq.eventloop import ioloop

    from . import (constants, error, message, context,
ImportError: libsodium.so.23: cannot open shared object file: No such file or directory

我已经用它来做 python 的工作一年了，感谢任何帮助。

尝试通过在 conda 中安装缺少的库来解决它。输入终端：

conda install -c conda-forge libsodium
