Dev process: npm i (or npm ci) freezes / takes too long

[xl0]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

I want to hack a bit. Following https://github.com/microsoft/vscode-jupyter/blob/main/CONTRIBUTING.md I ran
npm ci
and it hangs after a while, not showing any progress for over 15 minutes, and not showing up in top.
I see that in CI you use npm ci --ignore-scripts --prefer-offline --no-audit

In my limited experience with node, I've never faced this issue, so not sure if it should be fixed, or the docs should be updated.

(I installed recommended node version through mamba, and then installed the recommended npm version)

I also had to run
npm run postinstall
To actually get a working environment. But at least it worked. Is this a bug, or just lack of documentation?

Sorry for never getting back to you. Are you still running into this issue.
We used to have similar issues, however that was related to an npm package that has since been removed.

$ npm i
npm WARN deprecated [email protected]: This package is no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.
npm WARN deprecated @types/[email protected]: This is a stub types definition. del provides its own type definitions, so you do not need this installed.
npm WARN deprecated [email protected]: postinstall-build's behavior is now built into npm! You should migrate off of postinstall-build and use the new `prepare` lifecycle script with npm 5.0.0 or greater.
npm WARN deprecated [email protected]: CircularJSON is in maintenance only, flatted is its successor.
npm WARN deprecated [email protected]: lolex has been renamed to @sinonjs/fake-timers. No API changes made. Please use the new package instead
npm WARN deprecated [email protected]: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated [email protected]: This package has been renamed to @vscode/debugprotocol, please update to the new name
npm WARN deprecated @babel/[email protected]: 🚨 This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the @babel/polyfill docs (https://babeljs.io/docs/en/babel-polyfill) for more information.
npm WARN deprecated [email protected]: https://about.codecov.io/blog/codecov-uploader-deprecation-plan/
npm WARN deprecated [email protected]: You can find the new Popper v2 at @popperjs/core, this package is dedicated to the legacy v1
npm WARN deprecated [email protected]: TSLint has been deprecated in favor of ESLint. Please see https://github.com/palantir/tslint/issues/4534 for more information.
npm WARN deprecated [email protected]: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

thats so weird, I'm assuming you are using the asme version of node.js 18.15.0?

[xl0]

My bad, I had 18, but 18.20 because .15 is broken in mamba.
I downgraded to .17 which is the lowest that can be installed, and now it works!
