Incompatible with transform-es2015-modules-systemjs

[gajewsk2]

I get 'Unhandled promise rejection', Error{message: 'Module http://localhost:9877/src/hello.es6.js interpreted as global module format, but called System.register.

    babelPreprocessor: {
      options: {
        "plugins": [
          "transform-es2015-modules-systemjs"
        ],
        "presets": [
          "es2015"
        ],
        sourceMap: 'inline'
      },
      sourceFileName: function (file) {
        return file.originalPath;
      }
    },

Any ideas how to address it?

I'm not familiar with that plugin. What's does it do?

You can already use ES2015 style modules with JSPM.

So by default your modules will use the global format with es2015 preset. This plugin tells babel to use the SystemJS module syntax. Module Formats If I'm being honest I'm still not sure what the advantage of the SystemJS syntax is. @guybedford might have some insight on this.
