Question

我一直在尝试使用以下方法为Plotly安装Jupyter-Lab渲染器支持：

(base) C:\>jupyter labextension install jupyterlab-plotly

错误消息：

Building jupyterlab assets (build:prod:minimize)
An error occured.
RuntimeError: npm dependencies failed to install
See the log file for details:  C:\Users\<user>\AppData\Local\Temp\jupyterlab-debug-kyq0fo9a.log

如果我尝试使用--no-build命令安装扩展程序，则在尝试运行jupyter lab build时会遇到相同的错误

我还尝试通过conda install nodejs并通过浏览器安装来安装node.js。两者都以相同的结果结束

规格：

Windows 10
Python 3.7.6
Nodejs 10.13.0
Jupyter-Lab 2.1.4
密谋4.8.1

这可能是由于防火墙和任何最终陷阱所致。尝试暂时禁用这些功能，看看是否能够安装。
