尝试运行 jupyter 笔记本时发生导入错误

我正在尝试使用 anaconda (git bash 平台)运行 jupyter 笔记本，当我输入 jupyter 笔记本，每次导入都会出错。我尝试在环境中启动它，但发生了同样的错误。

$ jupyter notebook

回溯(最近一次调用最后一次):

    ImportError: DLL load failed: The specified module could not be found.

已编辑重新安装pyzmq(我也尝试重新安装conda)后，出现以下错误:

$ jupyter notebook

Traceback (most recent call last): File "C:\Users\User\Anaconda3\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 10, in import sqlite3

ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

我找到了similar issue在 GitHub 上打开 zmq。 GitHub用户推荐harsh23tyagi对大多数人来说似乎有效的是运行以下命令:

pip uninstall pyzmq
pip install pyzmq
