Error: Cannot find module 'loopback' in nodejs

I am facing below issue and unable to figure out the root cause.

Error: Cannot find module 'loopback'

Below are the dependencies I have in my package.json

"loopback": "^3.19.0",
"loopback-boot": "^2.6.5",
"loopback-component-explorer": "^6.0.0",
"loopback-connector-postgresql": "^2.9.0"

First I did npm i and then node .

But it throws an error Cannot find module 'loopback'

Don't understand why this is behaving differently. Please suggest

Edit: My all modules are found under

    > node_modules
      > .staging
        > //loopback modules and other modules are placed under .staging but not sure why.

The fact that your dependencies are inside the staging directory and not the main node_modules directory imply that something went wrong with the download/installation process and your dependencies are not installed properly. And hence you get the 'Could not find module' error.

Try the following steps -

  1. Delete package-lock.json
  2. Delete Node Modules folder
  3. Do a npm install to install packages listed in package.json

Once the installation is complete, all your node dependencies should be inside your node_modules folder.

It might also be worth checking to see if you have more than one node version on your machine. That could cause similar problems as well.
