Cannot read property '__useDefault' of undefined

I have a project that is using jspm-git to download code into the \jspm_packages folder.

Even though everything has downloaded fine, I am getting the following error:

aurelia-loader-default.js:55 Uncaught (in promise) TypeError: Cannot read property '__useDefault' of undefined
    at ensureOriginOnExports (aurelia-loader-default.js:55)
    at eval (aurelia-loader-default.js:247)
    at <anonymous>

Any ideas how I can fix this, or debug this, etc ?

Thanks

For NPM scoped packages make sure you properly include the dependency on aurelia.json, as they indicate here: https://aurelia.io/docs/build-systems/aurelia-cli#adding-client-libraries-to-your-project

 "dependencies": [
    {
      "name": "@scope/packagename",
      "path": "../node_modules/@scope/packagename/dist/amd",
      "main": "packagename"
    }
  ]

For example, for adding the aurelia-kendoui-bridge you would add this:

{
  "name": "aurelia-kendoui-bridge",
  "path": "../node_modules/aurelia-kendoui-bridge/dist/amd",
  "main": "index"
}

Most of the time the developer of the library will provide documentation for configuring the dependencies on Aurelia.
