解决方案在答案中

推荐答案

如日志文件所示，问题似乎是我的anaconda环境中的node已过时.

The issue, as indicated by the log file, seemed to be that the node in my anaconda environment was outdated.

$ type node
node is hashed (/home/***/anaconda3/bin/node)

$ node --version
v6.13.1

查看我机器上的nodejs:

Looking at the nodejs on my machine:

$ type nodejs
nodejs is hashed (/usr/bin/nodejs)

$ nodejs --version
v10.15.2

要解决此问题，我做了以下事情:

To get around this issue I did the following:

1. 导航到node的父目录
2. 以防万一，备份了node
3. 对nodejs进行符号链接，在此将其命名为节点"
4. 运行版本
5. 启用了jupyterlab-plotly扩展名
6. 重新启动Jupyter Lab服务器

1. Navigated to node's parent directory
2. Made a backup of node just in case
3. Made a symlink to nodejs here named as "node"
4. Ran the build
5. Enabled the jupyterlab-plotly extension
6. Restarted the Jupyter Lab server

命令如下:

cd /home/***/anaconda3/bin/
cp node node_bak
rm node
sudo ln -s /usr/bin/nodejs /home/***/anaconda3/bin/node
jupyter lab clean
jupyter lab build

一段时间后，构建成功结束.

After some time, the build concluded successfully.

我从内置扩展管理器中启用了jupyterlab-plotly扩展.然后我重新启动了服务器.

I enabled the jupyterlab-plotly extension from the inbuild extension manager. And I restarted the server.

此后，我的漂亮情节开始按预期渲染. :)希望这可以节省您一些时间.

My pretty plots started rendering as intended after this. :) Hope this saves you some time.
