[bug\_fix] npm ERR\! code E404 Not Found — package or version missing

Check the exact package name and requested version in \`package.json\` for typos, case errors, or an accidentally pinned non-existent version. If the package is private, ensure you are authenticated to the correct registry \(\`npm login --registry=...\`\) and that \`.npmrc\` points to the right scope. Then clear the lockfile entry for that package and run \`npm install\` again.

Journey Context:
A teammate shares a snippet with \`npm install @ourco/[email protected]\`. You paste it and npm returns \`E404 Not Found\`. You assume the registry is down and retry, but it still fails. You check the package name carefully and notice the team scope should be \`@ourcompany/logger\`, not \`@ourco/logger\`. After correcting the typo the package resolves. In another case, a private package needs \`//registry.npmjs.org/:\_authToken=$\{NPM\_TOKEN\}\` in \`.npmrc\`; once you log in, the 404 becomes a 200 and the install proceeds.

environment: npm installs from the public registry or a private registry/scope; common with scoped packages and lockfiles. · tags: npm e404 not-found registry scoped-package private-registry · source: swarm · provenance: https://docs.npmjs.com/cli/v10/commands/npm-install\#registry
