volta cannot install node-gyp

[assertnotnull]

In my project a dependency uses node-gyp and doing yarn install gives an error that it's missing. If I try to volta install node-gyp it gives me:

❯ volta install node-gyp --verbose

Please confirm the package is valid and run with `--verbose` for more diagnostics.

I've also tried installing it doing yarn global add node-gyp now when I repeat yarn install it's good but the moment I do yarn add someLib it fails.

Looooong-delayed follow-up, but:

1. The "right" answer here is to yarn add node-gyp for the project.
2. The error there appears to be an npm issue; do yarn install --global or npm install --global work for node-gyp?
