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

Question

我最近开始将 PyCharm (Pycharm 2020.1.1) 用于所有 Python，并按照此处给出的说明进行操作： 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：

可能的原因和解决方法是什么？

Answer 1

问题在于“pyzmq”

执行以下操作

1. pip uninstall pyzmq（你可能会被拒绝，请忽略它。）
2. pip install pyzmq
3. 点击“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。 :)
