python - PyCharm - Jupyter Notebooks - DLL 加载失败：找不到指定的模块

问题描述

我最近开始将 PyCharm (Pycharm 2020.1.1) 用于所有 Python，并按照此处提供的说明进行操作： https ://www.jetbrains.com/help/pycharm/jupyter-notebook-support.html#get-started

但是，尝试在 PyCharm 上运行 Jupyter 笔记本中的任何单元格时，我仍然收到以下错误。我什至尝试运行一个空单元格以查看我正在导入的任何库是否存在问题，但是，它仍然会引发相同的错误：

这可能是什么原因和解决方案？

解决方案

问题出在“pyzmq”上

请执行下列操作

  1. pip uninstall pyzmq （你可能会被拒绝，请忽略它。）
  2. 点安装 pyzmq
  3. 单击“将此解释器注册为 jupyter 内核”（由 pycharm 提示）。

这对我有用，希望对你也有用。:)
