【问题描述】:
我在运行 jupyter nbconvert 时遇到问题。
它总是显示以下错误跟踪(即使是带有几个普通单元格的笔记本)
Traceback (most recent call last):
File "/home/miguel/.virtualenvs/ipython/bin/jupyter-nbconvert", line 11, in <module>
sys.exit(main())

module = __import__(package, fromlist=[obj])
TypeError: Item in ``from list'' not a string
这可能与我最近安装的 nbextensions 有关,因为几天前 jupyter nbconvert 命令曾经完美运行。
今天,我在安装 nbextensions 时遇到了一些问题。我尝试使用 conda,但当我按照here 的说明进行操作时,它终于奏效了。

您有
~/.jupyter/jupyter_nbconvert_config.py(或.json)文件吗?
