This issue went away after I deleted ~/.npmrc and uninstalled + reinstalled this version of node (using nvm)

[RavirajParab]

Could you please provide the detailed steps of how you resolved the issue. I am stuck

[trickpattyFH20]

1. delete node_modules/ in your project folder
2. delete ~/.npmrc
3. uninstall nodejs and npm
4. reinstall the latest nodejs and npm

(I am using nvm to manage my nodejs and npm installations, if you are using nvm then the last two steps are easy, if you did a manual installation, then the last two steps are a little more difficult. I recommend using nvm and removing any manually installed versions of nodejs and npm anyways)
