【问题讨论】：

实际上，您不应该使用基本环境。您是否尝试过创建虚拟环境来安装软件包？

我还没有创建虚拟环境。我在基本环境中尝试过。如果我创建虚拟环境，我可以通过 Jupyter Anaconda 使用它吗？

如果你在虚拟环境中安装 Jupyter，可以。

对不起，我忘了问，您使用的是 Miniconda 还是 Anaconda？如果使用 Anaconda，它会在基础环境中安装所有内容。就个人而言，我使用 Miniconda 并将所有东西安装在虚拟环境中，基础环境非常小。请参阅***.com/a/56504279 另请参阅github.com/tensorflow/tensorflow/issues/22794 您可能需要安装 MSVC 可再发行组件。

我正在使用 Anaconda，所以想知道为什么在基本环境中安装了所有东西后仍然会出现此错误。在继续使用基本 Anaconda 环境的同时更正此问题的任何建议？

【参考方案1】：

我能够解决这个问题，这似乎主要是由于 tensorflow 版本。下面是我使用 Anaconda Python (v3.7) 在我的 Windows 笔记本电脑上安装 witwidget 所遵循的步骤

pip 安装 pyhamcrest 点安装谷歌身份验证 conda 更新包装

现在是重要的部分。如果 tensorflow 版本 > 2.0，则需要卸载它。所以尝试运行这个命令来安装 tensorflow v 2.0

pip install tensorflow==2.0.0

然后执行这些命令就可以了

pip 安装witwidget jupyter nbextension install --py --symlink --sys-prefix witwidget jupyter nbextension enable --py --sys-prefix witwidget

谢谢！
