You can bypass https by using the commands given below:

  npm Config set strict -sl false  

or from https to the registry url Set or set the http:

  npm config as below: Registry = "http://registry.npmjs.org/"  

However, I believe that bypassing https is not a real solution, but we It can be used as a workaround
