ipywidgets - 无法安装 ipywidgets jupyter 实验室扩展

Question

我在安装 ipywidgets jupyterlab 扩展时遇到问题。我试着按照这个方向，我得到的消息Building jupyterlab assets (build:prod:minimize)如下：

$  conda install -c conda-forge nodejs

Collecting package metadata (current_repodata.json): done

Solving environment: done

# All requested packages already installed.
$ jupyter labextension install @jupyter-widgets/jupyterlab-manager
Building jupyterlab assets (build:prod:minimize)
$ 

在此过程之后，我收到如下错误消息ModuleNotFoundError: No module named 'ipywidgets'。

我试图用两种方法解决这个问题。

1. 我将此页面作为参考，然后输入了jupyter lab build --minimize=False. 但是，我收到了与以前相同的错误消息：

$ jupyter labextension install @jupyter-widgets/jupyterlab-manager
Building jupyterlab assets (build:prod:minimize)

2. 我将此页面作为参考。但是，当我尝试时$which nodejs，终端显示上没有任何响应。

如何解决此问题并安装 ipywidgets？

我的机器上的信息：

$ which node

===============================

1. 我将操作系统从 v10.15.14 更新到 v10.15.5。

2. 更新操作系统后，我重新尝试安装 ipywidgets，如下所示。
