Answer 1

Gehen Sie Ihren Ordner 09-mongodb, dann führen Sie npm install Befehl, dann führen Sie npm run start.

npm install -

This command installs a package, and any packages that it depends on. If the package has a shrinkwrap file, the installation of dependencies will be driven by that.

By default, npm install will install all modules listed as dependencies in package.json.
