Report #75065

[bug\_fix] npm ERR\! cb\(\) never called\! npm ERR\! This is an error with npm itself.

Clear the npm cache completely: \`npm cache clean --force\`. Delete \`node\_modules\` and \`package-lock.json\`. Ensure stable network connection. Run \`npm install\` again. If persistent, upgrade to npm 7\+ which has better error handling.

Journey Context:
Developer runs \`npm install\` on large monorepo. Progress bar freezes at 40%, then \`cb\(\) never called\` appears. Tries again, same. Deletes node\_modules, reinstalls, same. Frustrated. Finds StackOverflow answer: 'clean cache'. Runs \`npm cache clean --force\`. Deletes lock file. Reinstalls, works. Learns npm 6 is buggy, upgrades to npm 8.

environment: npm 6.x \(bundled with Node 10-14\), unreliable networks, interrupted installs. · tags: npm cache cb-never-called corruption eintegrity network · source: swarm · provenance: https://docs.npmjs.com/common-errors
