Why doesn't ember test work? And why is node_modules empty?

Question

JavaScript

Just started to deal with ember.
Created the first project, launched ember serve.
Everything works - the link localhost:4200 goes to the start page.
But when I tried to run ember test I got: node_modules appear empty, you may need to run npm install.
I opened the node_modules folder and it is empty. On the Internet, it is clear that I am not the only one with such problems.
How is it solved? I want to run ember test without any errors

Answer 1

You must first run npm install in the root directory of the project. This applies not only to ember, but also to any nodejs project containing third-party modules. The modules themselves will not be installed automatically (if this is not specified in your deployment script, of course).
