python - 在 pip 安装 nbinteract 后，打开 Jupyter-Notebook 时出现内部服务器错误

Question

我在 anaconda 中使用 Jupyter-Notebooks 有一段时间了，但是在 pip 安装 nbinteract 5 分钟后，它停止工作......使用 Python3 创建/打开新笔记本时，我只收到“500：内部服务器错误”。

运行 pip 检查时，我收到以下消息：

spyder 4.2.5 requires pyqt5, which is not installed.
spyder 4.2.5 requires pyqtwebengine, which is not installed.
qdarkstyle 2.8.1 requires helpdev, which is not installed.
pylint 2.7.4 has requirement astroid<2.7,>=2.5.2, but you have astroid 2.5.
nbinteract 0.2.6 has requirement nbformat<5,>=4.4.0, but you have nbformat 5.1.3.
nbinteract 0.2.6 has requirement traitlets<5,>=4.3, but you have traitlets 5.0.5.
flake8 3.9.0 has requirement pycodestyle<2.8.0,>=2.7.0, but you have pycodestyle 2.6.0.
flake8 3.9.0 has requirement pyflakes<2.4.0,>=2.3.0, but you have pyflakes 2.2.0.
autopep8 1.5.6 has requirement pycodestyle>=2.7.0, but you have pycodestyle 2.6.0.

我尝试安装和更新/降级某些版本，但不知何故我未能摆脱错误并使 Jupyter-Notebooks 再次工作。

有人知道我的问题的答案并且会很乐意提供帮助吗？
