Answer 3

For me, deleting package.lock was not enough. My IDE always said this error:

Unexpected token <

So what I did:

1. Removed package.lock file
2. In IDE: npm cache verify

3. I write in the plain command-line interpreter , NOT in IDE :

   npm install @angular/http
   

Answer 4

It's because of package-lock.json. I just run the rm package-lock.json and It works for me.

Answer 5

For me , removing package.lock did not work

Try the following steps

1- set registry to https://registry.npmjs.org/. http did not work and had to change it to https

npm config set registry https://registry.npmjs.org/

2- I am behind a corporate firewall so i had to setup my proxy and https-proxy accordingly in the format - http://yourproxyurl:port

npm config set proxy http://someproxyurl.com:8080
npm config set https-proxy http://someproxyurl.com:8080

3 - Set ssl to false

npm config set strict-ssl false

These steps worked for me. Hope this helps.

I just delete the package-lock.json and run npm i again, it works for me
