@maniacs Thanks for the suggestion. Yes, this is one of the Jalb3 features that I am really excited about. It would make installation and conda env construction so much easier! (However, I reckon that it is goid to take a while to get to that point).
In my case, I actually have 5 or 6 labextension that I ran into this SSL: Certificate_verify_failed. I only listed one for simplicity here. So I am really looking for a solution that could fix the underlying root cause. Thanks again!
