python - Anaconda Jupyter Notebook Kernel error ImportError: DLL load failed while importing win32api: The specified procedure could not be found

问题描述

我之前在 Visual Studio 代码中运行过 python 3.8 和 jupyter notebook。安装 Anaconda 后，我无法再运行 jupyter notebook，并且出现内核错误。

ImportError: DLL load failed while importing win32api: The specified procedure could not be found.

我已经尝试过conda install ipykernel --update-deps，conda install pywin32但问题仍然存在。我怎样才能解决这个问题？

解决方案

这个建议对我有用： pip uninstall pywin32 然后 conda 再次安装它： https://github.com/jupyter/notebook/issues/4980#issuecomment-663885620

如何使用 conda 中的 pip：打开 Anaconda。在主页下方的左侧窗格中选择环境。在您选择的位置右侧和“搜索环境”栏下方，您应该看到 base(root)。点击它。应该出现一个指向右侧的三角形，单击它并选择“打开终端”在此处使用常规 pip install 命令。

然后如何使用 anaconda 安装 pywin32：根据本网站https://anaconda.org/anaconda/pywin32以管理员身份从 anaconda 提示符运行 conda install ：

conda install -c anaconda pywin32
