Projects created with Ionic 2 do not execute

Question

I create my projects without problems, but at the command: ionic serve, I have the following result:

24 error You can get information on how to open an issue for this project with:
24 error     npm bugs ionic-hello-world
24 error Or if that isn't available, you can get their info via:
24 error     npm owner ls ionic-hello-world
24 error There is likely additional logging output above.
25 verbose exit [ 1, true ]

All new projects look like this. Older projects run normally. Can someone help me?

Answer 1

According to the error message, you may be running an older or incompatible version of node.js or npm. In this case, I recommend you try to install the most current version (if you don’t already have it). You can install by command prompt (assuming you are using Windows) usingnpm install -g npm-windows-upgrade.

Other than that, the message indicates that you can get more information from the bug by running the command npm bugs ionic-hello-world.
