Not a valid npm package

zxdawn commented 5 years ago

I try to install pyviz by:

jupyter labextension install @pyviz/jupyterlab_pyviz

But, I got this result:

Node v6.14.4

> /usr/bin/npm pack @pyviz/jupyterlab_pyviz
|DNS-request| registry.npmjs.org ng node@v6.14.4
|DNS-response|: registry.npmjs.org does not exist
npm: ../deps/uv/src/unix/getaddrinfo.c:92: uv__getaddrinfo_translate_error: Assertion `!"unknown EAI_* error code"' failed.

Errored, use --debug for full output:
ValueError: "@pyviz/jupyterlab_pyviz" is not a valid npm package

Version of jupyterlab:

# Name                    Version                   Build  Channel
jupyterlab                0.35.6                   py36_0    conda-forge

It says "registry.npmjs.org does not exist", which looks to me like a temporary error due to a server being down; maybe try again?

It looks like I can't connect to the server in my university (China) ... Actually the log above is the result of proxychains jupyter labextension install @pyviz/jupyterlab_pyviz which uses the VPN.

Here's the original output of jupyter labextension install @pyviz/jupyterlab_pyviz:

Node v6.14.4

But, the VPN works for google and other websites ... It looks strange.

After killing all processes related to jupyter-lab, I still got the error.

This does not appear to be an issue with the extension itself, closing.
