Error with ionic-hello-world package


#1

I downloaded the Ionic and opened a project with version 2 (sidemenu project). When I write “ionic serve” command, the project works well without any error but when I want to close the node.js command line, I encountered the error in it that you can find below. For the solution, If I should update my npm and node.js how could I do those on Windows machine ? I am afraid of doing wrong things and losing the current working ionic mechanism and that is the reason why I ask this question. Also, it says that this problem is related with ionic-hello-world package. Thank you for your consideration.

I encountered the same error.

Running “npm install” will install the dependencies for the project which fixed the problem for me.
