`invenio buildall` results in `unable to resolve dependency tree` error

[thms-rmb]

Package version (if known): v1.2.7

Describe the bug

Unable to install with the invenio buildall command because of a dependency resolution problem. Actually, the problem can also be seen if I clone this repository and just run npm install directly in the assets directory.

Steps to Reproduce

1. Clone the repository (git clone https://github.com/inveniosoftware/invenio-assets.git)
2. Go into the assets directory (cd invenio-assets/invenio_assets/assets)
3. Do npm install
4. See the following error:

Expected behavior

I expect to be able to run the invenio buildall command (or alternatively just doing npm install directly in the assets directory).

Other things

I am using NPM version 8.5.5 installed with homebrew. I am running on MacOS Monterey version 12.1.

thank you for your contribution.
I would like to follow up on the issue before we integrate any change, due to potential implications for the whole invenio framework.
The invenio-assets module should be working with npm version 6, and node version 14. At the moment, we are not able to upgrade to npm 8 (the version which you have) due to significant breaking changes in NPM.
Could you test if the assets are building with npm 6?

[ZedThree]

I had the same problem and was able to get a bit further by running:

npm config set legacy-peer-deps true

which changes the dependency resolver npm uses to the legacy version.
