Error after installing the latest version of CLI package

[tawibox]

Hey guys,

Just installed the latest version CLI using this shell command on my mac OS:

npm install --location=global @gltf-transform/cli
(npm suggest use --location=global instead of --global)

this is the log after running this command:

npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: 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 request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

Some issues need review, and may require choosing
a different dependency.

Run `npm audit` for details.

Then when I was trying to run any gltf-transform CLI command I got this error:

Currently I am not able to use any gltf-transform CLI features.
Can anyone help me with it?
Also curious that is it only my case or someone else have smilar issue.

Many thanks
Tawibox

What command are you trying to run with gltf-transform? A good test that the installation is at least somewhat successful would be:

gltf-transform copy input.glb output.glb

If you're trying to do KTX2/Basis compression you will also need to install KTX-Software, a better warning message is needed for this though.

The warnings printed during the installation are just warnings, and can most likely be ignored.

[tawibox]

An update here. I found I ran into this error since 2.0.0. Any version 1.X.X I can use like before without problems.

[donmccurdy]

Oh! I think node v12 is the issue. Recent versions require v14+.

[tawibox]

Yes!! After upgrading node to v16 everything is working now. Thank you so much! @donmccurdy

[donmccurdy]

Hopefully the library will start warning automatically about this when #595 is published. :)

[tawibox]

Yeah that would be wonderful! Thanks again! ;)
