issue encountered while attempting to launch the server using grunt or node server

I'm currently attempting to utilize the Mean Stack framework, as outlined on their official website:

However, upon installation, I encountered an error while running "grunt": 

debugger listening on port 5858

Express app started on port 3000

events.js:72

Despite following the troubleshooting steps provided on the website, which included updating Grunt and clearing npm and bower caches, I continue to face issues. Even updating npm results in an error: 

npm ERR! error rolling back Error: Refusing to delete: /usr/local/bin/npm not in /usr/local/lib/node_modules/npm

This problem appears to be related to a conflict between Homebrew and npm, as discussed here: conflict between homebrew and npm. Nonetheless, I have version 1.3.21 of npm installed.

The same connection error occurs when I attempt to run node server.

Does anyone have suggestions on how to resolve this issue and get the server up and running smoothly?

Answer №1

Perhaps it's a simple oversight, but it appears that your MongoDB server is currently not operational. Once you've completed the installation of Mongo (presumably on your Mac), it is necessary to open a Terminal window or tab, execute the command mongod, and allow it to run continuously (or consider using screen or similar). To verify that the server is up and running, try accessing the MongoDB CLI by entering mongo.

Answer №2

@designl: Instead of constantly running the mongod command while using grunt, consider utilizing third-party services such as MongoDB Hosting provided by MongoLab at for a smoother experience. Hopefully, this suggestion proves to be helpful!
