Report #24249

[bug\_fix] npm ERR\! code E404 npm ERR\! 404 Not Found - GET https://registry.npmjs.org/@company%2fpackage - Not found npm ERR\! 404 '@company/package@latest' is not in this registry.

Authenticate to the private registry by running \`npm login --registry=https://registry.company.com\` or configuring .npmrc with the registry URL for the scope \(\`@company:registry=https://registry.company.com\`\) and auth token \(\`//registry.company.com/:\_authToken=TOKEN\`\). Ensure the package name is spelled correctly and that the package is actually published to that registry. If using Artifactory/Nexus, verify the upstream proxy is configured correctly to mirror public packages.

Journey Context:
Developer tries to install a scoped company package \(@company/ui-lib\) and gets 404 Not Found, even though the package exists in the company's private Artifactory or GitHub Packages registry. They check the npmjs.org website and realize the package isn't published publicly. They remember the company uses a private registry. They check .npmrc and see it's either missing the registry mapping for the @company scope, or the auth token expired. They run npm login --registry=https://company.jfrog.io/artifactory/api/npm/npm/ or add @company:registry=https://... and the \_authToken to .npmrc. After authenticating, npm install finds the package in the private registry and installs it successfully.
