NPM install error "Unexpected token < in JSON at position 0"

I'm using npm install and validate the package JSON content is valid and I'm getting the following error:

After reading on the web, I did "rm -f package-lock.json && npm install" (even if I didn’t see any package lock there) and did also npm cache clean -f which doesn’t help, also configured registry.

See Can't install any package with node npm

I'm using the latest npm, 6.2.0.

The error in the logs is:

Is there is something else I can do?

Solution

  • Your package.json, or maybe other JSON file is incorrect. You must first fix JSON errors.
