error with es-pack-js when executing 'npm i'

[letsgo0]

Hope someone know this problem. I just clone this repo, cd three-geo and npm i, then comes this error below.

node ./postinstall.js

Have you solved the problem yet？I ran into the same problem

Same here, can't get the example running locally

To my knowledge, this error happens when building on Windows.

Using the latest es-pack-js (v0.5.3 with partial Windows support) might help:

$ npm config set script-shell bash
$ npm i es-pack-js@0.5.3
$ npm run build

Updates (2022-03-22): As of 36f0862, building three-geo on Windows should just work by

$ npm config set script-shell bash
$ npm run build

[Bextia]

yes, I'm working on Windows.

I've tried your proposed solution and got this error on the second command:

[sonicviz]

Hello.

Windows user here, same error.

npm run build

three-geo@1.4.6-dev3 build
es-pack build -m umd

/bin/bash: es-pack: command not found

Any clues?

[j-devel]

/bin/bash: es-pack: command not found

Try npm i first?

[sonicviz]

Yes, already did fails.
Tried npm i es-pack-js@0.5.3 and fails.

Switching to WSL.

[j-devel]

Yes, already did fails. Tried npm i es-pack-js@0.5.3 and fails.

Please try npm i es-pack-js@0.5.13 (latest version 0.5.13, not 0.5.3). Still fail?

[sonicviz]

I switched to WSL2, installed nvm, node etc according to https://learn.microsoft.com/en-us/windows/dev-environment/javascript/nodejs-on-wsl

All checks out, everything installed. Opened Geo in VScode in WSL via code .

Try npm i or npm i three-geo but it fails now on: npm ERR! /bin/bash: node: command not found

But node is installed.

node --version
v18.12.1

Sorry, I am not familiar with the Windows environment...

FYI - latest CI build on Windows (via GitHub Action's Docker) https://github.com/w3reality/three-geo/actions/runs/4459639864/jobs/7832217785

[sonicviz]

Apologies. my mistake. I had skipped a step and VScode wasn't fully hooking into WSL when I booted the project.

Fixed it, and it's all working fine under WSL2 as per your original docs (after installing node etc as per MS instructions above).

Thanks for the help, sounding board helps troubleshoot. Sorry to bother you, but at least you can add some extra instructions perhaps for WIndows users now to use WSL. Microsoft actually recommends this for js development now anyway, so all good.

Looking forward to having a play with it, some great work you've done there!

You might be interested in what I want to add actually, could be a useful addition.
Haven't done three.js for a while so kind of starting from scratch again.

[j-devel]

@sonicviz I have added some notes regarding this.

Thanks for your interest, and looking forward to seeing enhancements!

[sonicviz]

No problem.

Q: How do you calculate terrain height relative to the position units in three.js, which are also dependant on the zoom factor?

For example, if I want to position an object 1m above sea level (which according to https://docs.mapbox.com/data/tilesets/guides/access-elevation-data/#mapbox-terrain-rgb sea level is 0) how do I translate that into a relative mesh position,z value that will translate it a unit of 1m (or 10m or whatever) relative to the scale of the mesh terrain elevation?

Also. how does that position calculation change based on the zoom factor, which can be from 11 to 17?

Okay, I think this is a different issue topic. Could you open a new thread?

[sonicviz]

aok, done. ty
