How to run "npm install" to create node_modules folder for an older Angular project?

Question

I'm pulling our code down from our repository to a new laptop. Our project was built on Angular 5 last year. Of course, the new laptop has the latest and greatest Angular CLI, NodeJS, and NPM tools install, and Angular 6 was just released. The laptop has Node 8.11.2, NPM 5.6.0, and Angular CLI 6.0.3.

When I run "npm install" to get the "node_modules" folder on my new laptop for this project, I'm getting all kinds of errors and warnings and unable to create the node_modules folder successfully (see image attached). What can I do to get this project running. I don't necessarily care about upgrading to Angular 6 at this time. I simply need to continue to be able to run and develop this project.

Our package.json:

}

Try running rm -rf node_modules and npm cache clean and do npm install — Gopakumar Gopalan

@Vikas, yes, that's what I'm trying to do. There's no node_modules checked in with our code, so I'm trying to run "npm install" to generate for this existing project. — Andy

@GopakumarGopalan Yes, I've done that, many times. Same results every time. — Andy

@Andy It seems like you are trying the right things. Have you tried these in an administrator console? — R. Richards

I faced a similar issue and removing the package-lock.json and running npm install solved it for me.

It is actually very simple. Just do a sudo npm install node_modules if you are using Mac/Linux or just a npm install node_modules on windows.
