Cannot install plugin: not a valid npm package #97

Hi, I am using Jupyter lab 1.1.4

When I did

jupyter labextension install jupyterlab_vim

I get an error saying that

An error occured.
ValueError: "jupyterlab_vim" is not a valid npm package
See the log file for details:  /tmp/jupyterlab-debug-i518ezyp.log

I also tried to install the plugin from within Jupyter Lab extensions manager GUI, and it is able to find "jupyterlab_vim" but again when I tried to install it, it complains with the same error message.

I solved the issue. It was to do with SSL certificates behind corporate firewall. I initially had both HTTP and HTTPS proxies set. This did not work, nor did setting strict-ssl to false in .npmrc work.

What worked for me was removing the HTTPS proxy, to force npm to use HTTP. After this, the plugin installed without issues.

Hey, I'm running into the same issue but I'm not sure what "removing the HTTPS proxy" means, could you possibly explain?
