Jupyter Lab

Extension 报 Error 500 的问题

应该是https的SSL网络问题，与VPN有关? 通过以下设置即可：

A quick solution from the internet search was npm config set strict-ssl false, luckily it worked. But as a part of my work environment, I am restricted to set the strict-ssl flag to false.

Later I found a safe and working solution,

npm config set registry http://registry.npmjs.org/  # 最终解决方案
