When a dependency has no matching version and another dependency peers on it,
npm installfailed withERESOLVE ... Found: <pkg>@undefinedinstead of the realETARGET.The failed fetch becomes a versionless load-failure node, and
#loadPeerSettreated it as a peer conflict before#pruneFailedOptionalcould report the load error.Both conflict checks in
#loadPeerSetnow defer when the conflicting node is a load failure, so non-optional failures throw their own error and fully optional sets are pruned as usual.References
