3. Run '...'
4. See error...

Environment

• npm:
• Node.js:
• OS Name:
• System Model Name:
• npm config:

; copy and paste output from `npm config ls` here

Start at node_modules/@npmcli/arborist/lib/arborist/build-ideal-tree.js:1289 and trace #loadPeerSet through buildIdealTree, using the supplied package.json and Node/npm versions to reproduce npm install. Done means the reported null edgesOut failure no longer occurs and the install completes; the issue does not name a regression test.
