npm loading failures in Node.js, Bun and Deno

These exact npm package versions had at least one recorded loading failure. Compare Node.js, Bun and Deno, then open the original report to inspect the failing import or require.

A failure here does not prove a runtime bug: the same package may fail in several environments. Missing optional peers, installation prerequisites, timeouts and service errors alone do not qualify a report for this list.

These are loading tests on Linux amd64 / glibc, with install scripts and execution networking disabled. Passing does not prove functional correctness. Versions listed here are tested versions, not necessarily the latest releases. Reports prefer the current environment and fall back to eligible earlier observations.
