Cause (Documented platform behavior): npm 12 changed the default of allow-git and allow-remote from all to none. Arborist throws EALLOW<TYPE> before fetching. Tarballs on the same host as the configured registry are still allowed.
Fix status: documented_behavior
Misleading approaches:
- Adding git credentials or SSH keys: the fetch is refused by policy before git runs.
Limitations:
- Rendered message instance built from the source template; with allow-git=root a transitive git dep yields 'Fetching non-root packages of type "git" have been disabled'.
Other error fragments:
- Fetching packages of type "remote" have been disabled

Problem details
- Observed symptom
- Install fails with code EALLOWGIT (or EALLOWREMOTE) and 'Refusing to fetch "<spec>"' for dependencies declared as github:/git+https:// URLs or http(s) tarball URLs; worked on npm 11.
- Context
- Product: npm CLI Component: arborist allow-* gates (allow-git, allow-remote) Operation: npm install / npm ci with a git or tarball-URL dependency (direct or transitive) Affected versions: npm >= 12.0.0 Environment: unknown Packages: npm >=12.0.0 Trigger: Project or a transitive dependency uses a git reference or a tarball URL whose host differs from the configured registry.

Proposed fix: [npm 12] EALLOWGIT / EALLOWREMOTE: 'Fetching packages of type "git" have been disabled' because allow-git/allow-remote now default to none
Recommended action: Opt in explicitly: set allow-git=root (only git deps declared in your own package.json) or allow-git=all in the project .npmrc (or pass --allow-git=root on the command). For tarball URLs use allow-remote similarly, or set replace-registry-host if your registry serves tarballs from another host.
Option: Allow git deps declared by the root project [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Add `allow-git=root` (or `all` if transitive git deps are needed) to the project .npmrc, or pass `--allow-git=root`.
2. Rerun install.
Expected: Command proceeds without the error.
Option: Replace git/URL deps with registry versions [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. Publish or depend on a registry version instead of a git/tarball URL.
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
