[bug\_fix] npm ERR\! code EBADENGINE

Switch to the correct Node.js version using nvm, n, or fnm, or use --force to bypass \(not recommended\). Root cause: The package.json 'engines' field specifies required Node/npm versions, and npm enforces this when engine-strict is enabled or by default in npm 8\+.

Journey Context:
You clone a repository from your company's monorepo and run npm install. Immediately you get 'npm ERR\! code EBADENGINE' with 'Unsupported engine' and 'wanted: \{node: ">=18.0.0"\}' but 'current: \{node: "16.14.0", npm: "8.3.1"\}'. You check your Node version with node -v and confirm you're on 16. You think about using --force flag, but you worry about potential runtime incompatibilities since the project explicitly requires Node 18 features like fetch\(\) or new V8 capabilities. You check if you have nvm installed by running nvm --version. You have it, so you run nvm install 18 and nvm use 18. You verify node -v shows v18.x.x. You run npm install again and it proceeds without the EBADENGINE error. If you didn't have nvm, you might have used n or fnm, or updated the package.json engines field if you were sure the version check was too strict, though that's risky.
