Fix: Error: Cannot find module '@babel/runtime/helpers/builtin/objectSpread'

Another common error: Error: Cannot find module '@babel/runtime/helpers/builtin/interopRequireDefault' How to fix: This has been traced in the forums as an incompatibility with the latest version of @babel/runtime. Change the corresponding line in the package.json file

  "dependencies": {
    "@babel/runtime": "7.0.0-beta.55",

and then do

meteor npm install
